Gonzalo Higuain could make his Chelsea debut in Sunday's FA Cup fourth-round clash with Sheffield Wednesday at Stamford Bridge (kick-off 6pm).
The 31-year-old striker completed his loan move from Juventus on Thursday and has been backed to hit the ground running with the Blues.
Chelsea assistant boss Gianfranco Zola said on Friday: "We're talking about a player who has scored not only in Italy but everywhere, also in the Champions League.
"I'm sure he can handle expectations. He's always produced good numbers wherever he's been. We're going to help Higuain to get his goals."
However, a decision is yet to be made on whether Higuain will feature against Sheffield Wednesday.
Zola added: "There are players who need to be rested and it could be an opportunity."
Meanwhile, interim Sheffield Wednesday boss Steve Agnew said Sunday's cup clash against Chelsea could not have been more timely for the club.
The Owls' trip to Stamford Bridge will be Agnew's last game in charge before he starts his role as Steve Bruce's assistant at Hillsborough.
"It's an amazing football club Sheffield Wednesday, fantastic fan-base and they will be very vocal on Sunday evening," he added.
"I don't think anybody involved in Sheffield Wednesday needs reminding because everybody realises how big the club is and the potential it has.
"But maybe a reminder to the rest of the football world that Sheffield Wednesday are playing in a huge game."

Chelsea changes are likely and Ruben Loftus-Cheek could be available following a back problem.
However, outgoing duo Victor Moses and Alvaro Morata are not likely to be considered.
