Former Chelsea striker Eidur Gudjohnsen has questioned whether manager Antonio Conte will be in charge next season.
Chelsea host Barcelona in the first leg of their Champions League last-16 tie on Tuesday night, before facing back-to-back Premier League away games at Manchester United and Manchester City.
"When you are manager of Chelsea, you are always going to be under pressure," Gudjohnsen told Sky Sports.
"But he is under slightly more pressure than he would like to be because recent results have not been good enough.
"Performances have not been good enough - yes they got the win the other night (against Hull City in the FA Cup) - but these next 10 days will tell us a lot about his future.
"The Chelsea of recent years have set a standard of at least challenging for the Premier League and they are not in the running anymore.
"So the focus goes on to staying in the top four and going as far as you can in the Champions League.
"And with that comes pressure as because you are not sitting too nicely in the Premier League and that makes these Champions League games even bigger."
