Roma president James Pallotta has insisted that he does not want star defender Mehdi Benatia to leave.
Swansea chairman Huw Jenkins has admitted Wilfried Bony could leave the Liberty Stadium if the 'right offer' is made.
West Brom defender Jonas Olsson wants to see who will replace head coach Roy Hodgson at The Hawthorns before deciding on his future.
Sweden international Olsson has just over 12 months remaining on his current deal with the Baggies and had originally wanted to wait until after Euro 2012 before making a decision.
But since then, Hodgson has become the new England coach and whoever takes over from him will have a big bearing on what option Olsson takes.
Olsson said: "I want to hold off definitely until I know who is going to be in charge. That's what I've been saying to Dan Ashworth (Albion sporting and technical director).
"It's important to know who is going to manage the club and I think that's a fair request before you speak about your future. That's where we are at the moment.
"Since New Year I have spoken regularly to Dan and, before the gaffer got the England job, it was very uncertain about his future here and that was my reason then for not speaking further.
"I wanted to know who was going to manage the club - and that is even more relevant now with the gaffer taking the England job."
However, Olsson rejects speculation that he has turned down an offer from West Brom.
He said: "That is not correct. We haven't spoken about figures or anything, we have just spoken about the future.
"It's not like the contract is running out this summer. It's a normal situation that most players with one year left on their contract speak to the club about their future and I've done that.
"There are a few bits that need to be sorted and the biggest bit for me is the management situation."
Olsson admits he will be in the shop window during Euro 2012 but his main focus is on success with Sweden who will take on Hodgson's England in their second group match on June 15.
He said: "Of course it (doing well) would be good for me but I am focusing on a team level first.
"You want to perform well to get into a good position but, if I am to speak about the future with West Brom, it's always good to have a good season behind you and also a good Euros.
"I will definitely want to play well for all those reasons but the first thing in my mind is to do well, so the Swedish team can do well."
Albion assistant boss Keith Downing concedes there is a feeling of uncertainty amongst players and staff with Hodgson departing after Sunday's home game with Arsenal.
He said: "It is unsettling for the players, for me, the staff. There is a sense of uncertainty but that goes for whenever anybody goes.
"It's a strange thing because usually when a manager leaves, it's through bad performances or a sacking. This is a success.
"To see somebody go in this way is a strange feeling and everyone feels a bit weird. But we're all professionals, the new man will have new ways and ideas and the players and staff will adhere to it."
Downing also believes Hodgson's appointment of Dave Watson as England goalkeeping coach for Euro 2012 may persuade Ben Foster to end his England retirement.
Foster worked with Watson last season at Birmingham before moving to the Baggies on loan.
Downing said: " I know Roy has spoken to Ben a couple of times on a personal basis.
"I have had no indications as to what was said, that's a private matter, but the fact Dave Watson is the coach might tip it.
"I think there was a good relationship between Dave and Ben and also Dave and Joe Hart from his loan spell at Birmingham."
Downing also hopes Albion pursue their interest in signing Foster on a permanent basis.
He said: "I think there's a respect for Birmingham. They're obviously licking their wounds after the play-off defeat.
"Ben has played exceptionally well and he's got better and better as the season has gone on.
"We would be stupid to turn that sort of interest (in signing Foster) away but I'm sure other clubs as well will be interested. We are trying to pursue that."
