Andre Villas-Boas has lamented the absence of John Terry, claiming being without his captain is a 'massive, massive loss' for Chelsea.
The 31-year-old has undergone knee surgery and will be sidelined for a further six weeks, having already missed a number of key games for the Blues.
Terry has not featured in any of Chelsea's last five encounters, all of which Villas-Boas' side have failed to win, highlighting the importance of the defender to the west Londoners' cause.
Not only have Chelsea failed to register a result of note in the absence of Terry, but they have also conceded ten goals, slipped off the pace in the Premier League, and seen their Champions League hopes severely dented.
And Villas-Boas recognises what a vital influence Terry has at Stamford Bridge - both on and off the pitch.
"We badly miss him. It is a massive, massive loss," said Villas-Boas, according to skysports.com.
"He is a leader and a great performer even through adversity."
He added: "He has had his knee operation and he will be out for between five and six weeks, hopefully sooner."
Chelsea face Bolton on Saturday afternoon, and three points will see them climb into the top four, with Arsenal not scheduled to play until Sunday.
