Champions League: Things we learned from Tuesday`s Matchday 5 showcase

New Delhi: Emphatic Barcelona and Bayern Munich continued their dream run and dominance in Europe to show why they are a class above the rest.

Meanwhile, English teams Arsenal and Chelsea notched big wins to bring much needed calmness around fans. With FC Porto losing to Dynamo Kyiv, Group G has opened up. A win for Kyiv in Gameweek 6 could determine fortunes of both Chelsea and Porto.

Valenicia's hopes have also been dented and Gent find themselves in a better position after win against Lyon.

Here are the five things we learned from Tuesday's Matchday 5 encounters.

MNS trio arguably the best together: Barcelona's trio of Lionel Messi, Neymar and Suarez have taken the level of football to a superior zone, where most teams cannot match at the moment. The trio's excellent link-up and understanding made the Catalans toy around with AS Roma. Luis Enrique's team not only dominated at the Camp Nou, but also displayed one of the best ever attacking vision in history of the sport.

Bayern in world of their own: Bayern under Pep Guardiola are winning almost every match they are stepping into. The Bundesliga leaders showed no mercy for Olympicaos after their possession based dominance just like Barcelona, made the visitors look clueless. The attacking brilliance of Bayern's superstars have ensured a carnage at goal-scoring. Ruthless Bayern have scored 16 goals in last five games

Arsenal look to believe under Wenger: With Champions League progression almost written off, Arsenal suddenly find themselves in the mix of qualification. Their 3-0 win against Dinamo Zagreb, see them take the fight until the last encounter of Group Stages. Arsenal need a victory in Greece and Wenger's experience and stability will be a pivotal factor in those circumstances.

Chelsea bounce back to show usual self: Chelsea showed they still have enough grit and fight to make something out of this stuttering season so far. Jose Mourinho's men registered their second consecutive victory in space of three days after beating Norwich earlier in the Premier League. Jose' who is a masterful tactician got his vision spot-on to get more confidence and belief in his side.

Zenit enjoying magical form: Russian giants Zenit St Petersburg have been the only team in the Champions League this term to register five consecutive victories. In-form Artem Dzyuba has been stupendous for manager Andre Villas Boas after being in superb goal-scoring form. Brazilian Hulk too has been a revelation so far as the Russian leaders brushed aside Spanish outfit Valencia 2-0. Zenit look like surprise contenders for doing something big this season.
