Matchday 4 of the UEFA Champions League takes place tonight which sees a number of top clashes take place. The likes of Chelsea, Juventus, Bayern Munich, Barcelona and Manchester United are all in action tonight, which promises to give us some exciting football.
Here, we take a look at the three things to look out for tonight.
1. Man United come into the game on the back of a much needed win
Ole Gunnar Solskjaer's side got a much needed win when they beat Tottenham Hotspur 3-0 in the Premier League over the weekend and they will look to continue that when they travel to Italy to face Atalanta.
United have history on their side as they have lost only one of their last 11 games against Italian opponents in the Champions League, and a win on the night would ensure that they record their 150th win in Europe - making them the first English side to reach this milestone.
2. Juve's league struggles not affecting them in Europe
Juventus might be currently struggling in the Serie A, but they have a perfect record in the Champions League so far, winning all the three games they have played so far.
The Bianconeri have won eight of their last nine home games in Europe and Max Allegri will hope that his side can continue their form in the competition.
3. Must win game for Barcelona
Barcelona have struggled so far in the Champions League, finding themselves placed third in Group E with three points from three games. The Catalan giants are in the doldrums having sacked Ronald Koeman as manager recently, and it will be interesting to see if interim boss, Sergi Barjuan can inspire them to win against a poor Dynamo Kyiv side.
