Lee Clark has spoken of his desire to keep as many of Blues' loans players as he can at the club next season.
The Blues boss currently has five in his squad - Ravel Morrison (West Ham), Paul Caddis (Swindon Town), Wes Thomas (Bournemouth), Shane Ferguson (Newcastle) and Jack Butland (Stoke).
Although he has already had strong indications from many of them that they would like to stay at St. Andrew's, he admits the decision will ultimately come down to what their parent clubs decide to do.
"I would like to make Paul's permanent," said Clark. "But he has got another year at Swindon and he's like a financial commodity to them.
"He is desperate to stay and we want him to stay and it would be a massive blow if itdidn't happen, that's for sure. The right-back position has been not so good to us but he has come in and made it his own and done terrifically.
"I have already been on record saying I'd love to get Shane on a season long loan again and we have started talks with Newcastle United on that.
"Wes I would like to keep, but I think he's going to be a transfer fee from Bournemouth, so obviously that's an area where I need to find out if it's do-able."
Clark continued: "People might think I'm crazy, but I'd like to have another year trying to take Ravel (pictured) to where he can go!
"That's because he has improved on lots of things, on and off the field. And we believe if we can get another year with him, we can continue that development. The thing for me is that he has shown the willing.
"I have said all along that there's no doubt about the talent and I think people are seeing that there's an unbelievable footballer in there. I know he has enjoyed his time here and I have spoken to the lad and if something could happen, he would be happy to stay here.
"Now, what we have got to do is have some sort of dialogue with West Ham to see if it is possible."
Regarding Jack Butland and his move to Stoke City, Clark admits that loaning back is probably unlikely, but he is not ruling it out should the opportunity arise.
"My personal opinion is that I think Jack will be playing in the Premier League next season," added Clark.
"We are not ruling it out, of course we are not. We have said all along that we have made it clear to Stoke that if that was the case, and they were going to loan him back in the Championship, we would be right at the top of the queue, we would want him.
"But we have also got to look elsewhere as well to make sure that if that doesn't happen we are covered. Loans happen so late but I think Stoke will inform us quite quickly of their decision because it all depends on what happens with their goalkeepers as well."
