BAYERN MUNICH star Ivan Perisic faces missing the Champions League showdown with Chelsea in a huge boost for the Blues.
Caretaker boss Hans Flick confirmed that the Croatian winger is out for at least four weeks after Real Madrid loanee Alvaro Odriozola broke his ankle in training.
Perisic, 31, is all-but certain to miss the first leg at Stamford Bridge on February 25 and is a doubt for the return on March 18.
Flick said: "He has a fracture at the outside of his ankle.
"It will take at least four weeks until it is healed and only then he will be able to start with building up training again."
Former Manchester United target Perisic was fouled by Odriozola - who only joined the club at the end of January - in training this morning and ended up with a fracture.
The World Cup finalist has five goals and eight assists this season and started five games in a row before his injury.
Flick has Philippe Coutinho and Serge Gnabry as options out wide but will miss one of his best creative outlets.
Bayern have been in good form since the winter break but went out of the Champions League at this stage last season against eventual winners Liverpool.
Frank Lampard, meanwhile, will hope his youngsters are ready for a high-pressure clash after failing to land any new additions in January.
