On paper, it seems a no contest. German champions Bayern Munich look outrageous favourites versus Lyon, who finished seventh in French Ligue 1, for Wednesday’s Champions League semi-final.

But on the ground, the mighty Germans may not find it easy, not after Lyon punched above their weight in outclassing Cristiano Ronaldo’s Juventus and Pep Guardiola’s Manchester City.

That is the reason why Corentin Tolisso says treble-chasing Bayern should be wary of his former club Lyon.

Make no mistake, the Bavarians are the favourites. They cannot be anything else after they stripped naked Lionel Messi’s Barcelona 8-2 in the quarter finals. They are a well-oiled machine — their football flowing freely, their defence standing tall and their attack coming in waves. The likes of Thomas Muller and Robert Lewandowski have looked hungry for success.

But midfielder Tolisso, who joined Bayern from Lyon in 2017, has a point. “From a German point of view, perhaps Lyon’s the least known team. But against Manchester City, we all saw what this team is capable of. We will never underestimate them. When the big games come up, Lyon is always there.

“No team can reach the semi-finals by chance,” said the 2018 World Cup winner, who is likely to start on the bench on Wednesday.

In the wake of their stunning thrashing of Barcelona, there is an air of determination in the Bayern camp.

Defender Jerome Boateng has compared the current squad to the 2013 outfit who landed the first treble of Bundesliga, German Cup and Champions League titles in the club’s history.

“To be honest, I noticed from day one that something was up,” remembers Boateng of the 2013 squad. “That was our big goal for the season.

“We played better in the Champions League from the start than we might have done in the Bundesliga. We were extremely greedy all the time.”

The current crop of Bayern stars has the same insatiable appetite, earning the nickname ‘FC Never Satisfied’ by the German media.

Bayern’s average of 4.33 goals per game is a new Champions League record. They have scored 39 goals in 9 European games, including a 7-2 drubbing of Tottenham and a 6-0 romp at Red Star Belgrade.

Lewandowski is the competition’s top scorer with 14 goals — three short of Cristiano Ronaldo’s 2013-14 record for a Champions League season.

However, nothing is being taken for granted against Lyon.
