The Champions League is getting close to its most crucial stage, and some top clubs have already qualified for the competition's knockout stage.

Others are struggling and risk being dumped out before the next tournament round, making matchday five an important one.

This season has been one of the most exciting yet competitive in the recent competition's recent history as several clubs defy the odds to cause some upset.

Manchester United fans were delighted to see their team back in the competition and were confident they would do well.

Some pundits even tipped them to win it, but Erik Ten Hag's side could be dumped out of Europe entirely after matchday five.

Sevilla is another struggling giant and they could finish the competition without a place in the Europa League as the likes of Lens and PSV prove too strong for them in Group B.

Newcastle United started their European campaign very well. It defeated PSG 4-1 in front of their fans, but they are at the bottom of their group after back-to-back losses against Borussia Dortmund.

But that group is the closest in the competition, and matchday five will separate the boys from the men.

In group H, Barcelona also finds itself in a tight situation as the top three could all finish as group winners.

Xavi Hernandez's side faces a tough FC Porto team on matchday five and knows it is a must-win game if they want to top the group.

Every Champions League ticket holder wants to watch the most exciting game in this round and we have curated a list for them.

AC Milan vs Borussia Dortmund

AC Milan and Borussia Dortmund are two of four teams in a very tight group F alongside Newcastle United and PSG.

Dortmund tops the standings with seven points, while Milan has five points and is third.

This game offers the Serie A side a chance to finish this match second in the standings if they can win.

A win for Dortmund extends the German side's lead at the top and could be the end of the Champions League road for Milan.

The first leg between these teams in Germany ended in a goalless draw and both clubs have enjoyed contrasting fortunes since then.

Milan has struggled domestically and in Europe, leading to their manager's sacking. But BVB has won two matches against Newcastle United to make themselves the top side in this group.

PSG vs Newcastle United

PSG gets a chance to avenge their defeat in the first leg after Newcastle United blew them away in a 4-1 loss at St James Park.

The Magpies are back in the Champions League after two decades, and the win in the first leg was a serious show of intent.

But since then, they have struggled and lost back-to-back games against Borussia Dortmund, which is hardly the best way to prepare for this game.

PSG, on the other hand, has done poorly on the road as well, but they have a superb home form, which will give them an advantage in this game.

Newcastle knows they cannot afford a defeat, and some of their many injured players will be back to fitness after the international break.

The Magpies may not win as well as they did in the reverse fixture, but they can make this game exciting.

Barcelona vs FC Porto

Barcelona finds itself atop the standings in Group H after four Champions League games, which is exactly where they want to be.

However, they are level on point with FC Porto ahead of this game, making the tie arguably the trickiest they will face.

The Portuguese side has a serious European pedigree and is showing again why they are one of the top sides in their country.

Barca would have felt more comfortable heading into this game if they had secured a positive result in their last match, but Shakhtar Donetsk beat them.

Now they must beat Porto because if they lose and the Ukrainians defeat the Whipping boys in their group, Royal Antwerp, they will be level on points heading into the last group game.

Porto will also be eager to seal qualification for the next round in Spain and can only achieve this with a positive result in this game. We expect them to deliver a masterclass.

Galatasaray vs Manchester United

Manchester United is on the verge of being dumped out of the Champions League and all European competitions in the group stages.

When the draw was made, fans expected the Red Devils and Bayern Munich to qualify for the knockout stage of this group.

However, after three losses from four group games, United faces an early exit from Europe despite facing Galatasaray and FC Copenhagen.

This game is a chance for them to avenge the shock defeat they suffered at the hands of Galatasaray in the first leg.

Erik Ten Hag's side could not take advantage of a loud Old Trafford to secure even a point in the reverse fixture. Their fans will worry if their team has what it takes to win in Turkiye.

Gala knows a victory in this game will almost certainly guarantee them passage to the next round of the Champions League, and they will work hard to earn all the points.

Sevilla vs PSV

Sevilla has traditionally done badly in the Champions League, but they always try to finish third in their group to secure a spot in the knockout stage of the Europa League.

That could be much different in this campaign as they languish at the bottom of their Champions League group.

The Spanish side has just two points from four games and faces a PSV side that is second on the table with five points.

The Dutchmen will be keen to secure at least one point in this match, knowing that Arsenal will almost certainly defeat Lens.

But a Sevilla win will make things even more interesting as they will have five points and all three sides, apart from Arsenal, will be level on points on the final matchday.

This is why this game is probably the most crucial fixture both clubs will play in the coming weeks, and it will be interesting to see how this group looks after matchday five.

Benfica vs Inter Milan

Benfica has had a terrible Champions League campaign, which has been a huge shock because they were in good shape domestically and in Europe last season.

The Portuguese side has traditionally been one of the top clubs from its country in Europe, but they have earned zero points so far ahead of this game.

Inter Milan reached the final of the Champions League last term and has collected ten points from their opening four matches.

The Italians are unbeaten so far, while Benfica has lost all four games, but the Champions League is a competition made for upsets.

Benfica tops the standings in the Portuguese league despite having a terrible campaign in Europe. They have nothing to lose, and this game could be the fixture they return to form.

Inter might feel too confident in their ability to win this game and underestimate the threat from Benfica, which could hurt them.

Conclusion

Matchday five of the Champions League is a definition of the business end of the competition and these are the match tickets you want to take advantage of.
