Manchester United manager Louis van Gaal has refused to rule out the possibility of signing goalkeeper Victor Valdes.
Manchester City boss Manuel Pellegrini says he is confident that England goalkeeper Joe Hart will sign a new contract.
Chelsea interim manager Rafa Benitez believes his work with the Blues will stand him in good stead when he begins his search for a new job in the summer.
The former Liverpool boss has endured a fractious relationship with the club's supporters since his appointment as Roberto Di Matteo's successor earlier in the season.
Despite being knocked out of three competitions since Benitez's arrival, Chelsea remain in contention for silverware in the Europa League and are battling with London rivals Arsenal and Tottenham to secure a top-four finish in the Premier League.
Benitez said: "I have a contract until the end of the season and then we assume that's it.
"I have to do my job. If you are asking me how I will be remembered - professional, working hard and trying to do my best.
"People can see what I have achieved in the past. We are talking two years ago, not 20 years ago.
"If you are at a top side, everyone can see you.
"I'm managing a top side and in the circumstances we are doing a good job. We can achieve another title and finish in the top three."
