England goalkeeper Fraser Forster does not know if he will still be at Celtic when they next play in Europe.
Norwich captain Sebastien Bassong has signed a new two-and-a-half-year contract.
Juventus are refusing to give up in their chase for Real Madrid's Gonzalo Higuain amid reports that Arsenal have reached an agreement with him.
The Gunners have been favourites to do a deal ever since it emerged that the striker could be lured away from the Bernabeu.
Juve will not be giving up without a fight, though, and general director Giuseppe Marotta believes there could be a late twist in the saga.
He told Sky Sports: "Higuain? I do not want to say anything because there is still so much time left for things to happen."
With a striker considered to be Juve's top priority this summer, they have also been linked with moves for Fiorentina's Stevan Jovetic and Manchester City's Carlos Tevez.
Marotta is, however, keeping his transfer cards close to his chest.
He added: "There is no hurry. They are both great players but they are also with great clubs, so it would not be right to discuss them.
"I do not want to create an illusion that things are already in motion."
