Celtic claim a fee was agreed with Manchester City for John Guidetti prior to them taking the striker on loan.
Xabi Alonso claims no Premier League offers were put to him before leaving Real Madrid for Bayern Munich.
Peter Odemwingie has been told that he will not be allowed to leave West Brom during the current transfer window, the club's new sporting and technical director, Richard Garlick, has confirmed.
The Baggies striker is a target for QPR who have already had one offer rejected - believed to be £2million.
But Garlick insists the Baggies will only allow players to leave on their terms.
He said: "Last summer there were supposedly players leaving but we kept hold of most of them.
"We don't have to sell any of our players. It's only on our terms.
"It's well documented about Peter. We had an offer and we don't intend to sell any of our players.
"When an offer comes in, we speak to the player out of courtesy. We've had that chat with Peter and he knows the situation."
Albion also rejected a £5m bid from Rangers for defender Jonas Olsson who only signed a new four year contract in October.
Garlick does not expect West Brom to sign any players before the transfer window closes a week today.
He said: "We're happy with the squad we've got and there are no immediate plans to bring anyone in.
"If an opportunity presents itself, then we will look at that, but we're looking more towards the summer."
