Bayern Munich midfielder, Thomas Muller says Sadio Mane has jokingly warned him not to “mistake” and pass to Robert Lewandowski as Bayern Munich and Barcelona square off today.

The two sides clash in the Champions League on Tuesday at the Allianz Arena, Munich, with each of them aiming to continue their perfect starts to the campaign. German champions Bayern earned a 2-0 victory over Serie A giants, Inter Milan on the opening matchday, whilst the Catalans thumped Viktoria Plzen 5-1.

The hotly-anticipated showdown will be an emotional occasion for Polish striker Robert Lewandowski. He makes his first return to Bavaria since quitting Bayern Munich for Nou Camp earlier this summer.

In an amusing message, former Liverpool forward, Mane has warned new teammate, Muller to ensure he doesn’t pass to Lewandowski out of habit.

As quoted by Spanish outlet Sport, the German international said: “Sadio has been joking, telling me not to make a mistake and pass the ball to Lewandowski during the game. We have to play our game tomorrow and not focus too much on Lewy.”

It will be a strange fixture for Muller in light of the potent, often-telepathic relationship that he struck up with Lewandowski. In eight years as teammates, the pair won eight Bundesliga crowns, three German cups and the Champions League.

Speaking further about his relationship with the Pole, Muller said: “Our connection on the pitch grew over time. But now we have a lot of versatile players up front and we don’t have a single reference. Opponents don’t know who the regular striker is and we have to make it work.” He concluded.
