File Picture[/caption] Internet Desk : La Liga giant Atletico de Madrid is all set to take on Bundesliga champion Bayern Munich tomorrow in the UEFA Champions League at the Vicente Calderon Stadium. Atletico de Madrid is still unbeaten this season and will look to extend that run against Carlo Ancelotti's men. Diego Simeone’s men have looked an extremely good defensive unit but have struggled to score goals at times despite having stars like Antoine Griezmann, Fernando Torres and Gameiro in the side.

Matches against Leganes, Deportivo, PSV and Barcelona show that the Spanish club needs to improve in their attacking front. Versus a top graded side such as Bayern Munich, any flaw will be merciless and it will be interesting to see if Simeone changes his approach to help creating more chances for his attackers with a 4-3-3 formation.
Group leaders Barcelona will lock horns with German club Borussia M'gladbach. In an away game, it will be a testing time for Luis Enrique as they won't be having their superstar Lionel Messi. Though the recent form of Neymar Jr and Luis Suarez can ease the pressure a little bit from the Spanish giants.
Arsene Wenger's Arsenal will be high on confidence when they will host Basel at the Emirates. The 3-0 victory over Antonio Conte's Chelsea last week will certainly give them the edge in the important Champions League tie against Basel. Alexis Sanchez & Theo Walcott's recent form has now very well complimented by Mesut Ozil, Sir Arsene Wenger can breathe easy.
In another crucial game, Scottish giant Celtic will take on Pep Guardiola's Manchester City. This will be the first ever meeting between these two sides in any European competition. The recent form of Pep's men in the champions League will certainly give confidence to the whole unit as they won seven games off their last nine UCL appearances.
Paris Saint Germain will be playing Bulgarian side Ludogorets Razgrad away in another tie. This will be the first ever meeting between these two sides. It will also be the first time when a French club will be taking on a Bulgarian club in a Champions League clash.
