Birmingham have offered new contracts to four players as they continue talks with goalkeeper Darren Randolph.
Wolves' Bakary Sako has revealed he is mulling over offers from the Premier League but is yet to decide on his future.
West Ham forward Ricardo Vaz Te believes everyone at the club loves having Andy Carroll around and wants to see the England international join on a permanent deal in the summer.
Carroll, 24, is currently on loan at Upton Park from Liverpool and, despite a mixed start to his time with the Hammers, he has started to prove his worth to Sam Allardyce's side.
The former Newcastle striker has scored six goals so far this campaign and put in a man of the match performance for West Ham in their 2-2 draw against Manchester United on Wednesday night.
Vaz Te, who opened the scoring in the game after latching on to a Carroll knockdown, is a big fan of the frontman and feels he can offer plenty to the side.
"He is very valuable for us and since he came to the club he has been great to be fair," he said.
"He works very hard, holds up the ball and takes pressure off the lads, he is terrific really.
"I call him a beast. He is great in the air and he can chest and head and his accuracy is perfect, he is good on the floor as well - he can play with the ball."
Liverpool spent £35million to prize Carroll away from Newcastle in January 2011 but he struggled for goals and was allowed to move away on a temporary basis when new manager Brendan Rogers arrived at Anfield.
Vaz Te reckons Carroll, like so many players, thrives on self-confidence and the feeling of not being appreciated at Liverpool took its toll.
"He is like every player, you can go from the lowest to the top if you don't get games and that playing time or the confidence from your manager and team-mates - it is never going to work." Vaz Te added.
"You need a routine and you need trust from your manager. Here we all love him and we all care. We all admire him and that has given him that confidence and he has flourished."
Allardyce has made it clear that he would like to retain Carroll's services next season, although he did suggest the incoming financial fair play rules could scupper any potential deal.
Vaz Te, who played under Allardyce at Bolton, certainly wants Carroll to stick around if at all possible.
"If we can keep him next season that would be great - it depends on him but it would a huge step forward," he said.
"I think there are financial issues and that is nothing to do with me but I think every player, the coaching staff and the fans would love to keep him, we are all happy to have him."
Carroll's performance against United certainly caught the eye, not least of the Red Devils' boss Sir Alex Ferguson who claimed he should have been sent off for an aerial challenge on David De Gea.
Allardyce dismissed those suggestions but was left ruing a decision by assistant referee Harry Lennard that allowed Robin van Persie to grab a share of the spoils for the league leaders.
The Dutchman pounced on a loose ball to snaffle away his chance but appeared to be in an offside position when he did so prompting Allardyce to claim his side had been robbed of a "famous win", with the Football Association confirming on Thursday that the West Ham chief would not face disciplinary actions for his comments.
