Didier Drogba will start for holders Chelsea in their FA Cup Fourth Round replay at home to Everton on Saturday after losing his place to Fernando Torres in the drawn Premier League match against Fulham on Monday.
"Drogba will start, but I have to choose the striker to use with Drogba," coach Carlo Ancelotti told the club's website on Friday.
"I saw the same Didier, in focus on the training working hard with good motivation, and I think he will play a fantastic game."
Sir Alex Ferguson says Manchester United's fifth-round tie with minor league Crawley Town at Old Trafford is evidence that there is plenty of life left in the FA Cup.
"They talk about the FA Cup dying but it won't die as long as you've got giant-killing acts that Crawley have already produced," said Ferguson as he seeks to extend United's record number of Cup final wins to 12.
"It will be brilliant for the Crawley fans but their team's performances against Derby County, Swindon and Torquay tell you they deserve to be in this round.
"We respect the fact that Crawley are the best non-league side for quite a while," added Ferguson, who needed replays to get past minor league Exeter and Burton Albion in 2005 and 2006.
Conference side Crawley visited Old Trafford on Thursday night and took the "visitors' tour" - complete with recordings of great nights at the stadium - to get some idea of the noise and atmosphere that awaits them on Saturday.
Centre-back Johan Djourou is out, after hurting his back on Wednesday, along with the suspended Abou Diaby but "forgotten" striker Marouane Chamakh will return to the squad.
"There will be some rotation," said manager Arsene Wenger. "We play Sunday, Wednesday and then Sunday again."
