Roberto Di Matteo has admitted Fernando Torres may be at risk of burnout as he prepares to ask the striker to lead the line for Chelsea on Saturday.
Torres looks set to maintain his record of starting every one of the European champions' games this season when they take on Norwich City in the Premier League.
The match is Chelsea's seventh in just 21 days, a punishing schedule that has seen manager Di Matteo take every opportunity to rotate his squad.
He almost certainly would have rested Torres during the past three weeks but for an injury to Daniel Sturridge, who is the club's only other recognised senior striker.
And Di Matteo admitted it was something he might need to address after Torres returns from the upcoming international break.
Asked if burnout was a concern, he said: "It's our seventh game tomorrow in 21 days and he's in good shape, he's very fit. But, certainly, it's something we have to look at."
