Olympiakos a Difficult test- Simeone

The Argentine highlighted the strength of their Greek opponents in front of their home support and is anticipating a difficult night's work in the Champions League on Tuesday

Diego Simeone says Atletico Madrid will face their most difficult test in Champions League Group A when they take on Olympiakos in Greece on Tuesday.

The Greek Super League champions won 16 of their 17 league fixtures at home last season, as well as defeating Manchester United in the first leg of their last-16 European tie before exiting the competition after a second leg defeat.

Atleti finished runners-up themselves in the competition last term, but Simeone is wary of just how tough a proposition Olympiakos could prove to be.

He said: "Tomorrow morning we will decide the starting lineup. This will probably be the most difficult game in the group; Olympiakos have a very strong home record and passionate fans. We had a great season last year. But that's in the past. We are starting from scratch again. We are building the team day by day."

The Argentine is familiar with Olympiakos boss Michel having come up against him during his playing days and was quick to praise him for giving his side an identifiable style of play.

"I''ve played against Míchel as a player and coach," he added.

"Míchel had a great run with Olympiakos in the Champions league. He's succeeded in giving Olympiakos a distinct style and character. He has put his stamp on the team."
