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.
Arsene Wenger has again ruled out leaving Arsenal before the end of his contract - and hinted for the first time he would like to stay on past 2014.
The Gunners boss, 63, still has another season left to run on his current deal, but has been linked with a summer switch to big-spending Paris St Germain.
Wenger, though, stressed his only focus was on securing Arsenal a top-four finish in the Barclays Premier League again and then planning to further strengthen the squad in the transfer window, with the best part of a £100million warchest at his disposal.
Speaking at Friday morning's media conference ahead of the trip to relegated QPR, Wenger said: "I answered that question already. I respect my contracts.
"I want to stay (on past 2014) if I do well and if I consider or the club considers that I do well, that is all.
"I want this club to do well, that is my basic feeling.
"We have gone through a period that was very sensitive, we are coming out of it now, in a much stronger position financially.
"I believe the club is in a very strong position for the future."
