Mahrez made it clear at the end of last season that he would be looking to leave Leiceste rthis summer and recent reports have claimed that the Algerian international has been subject to a big money bid from Italian side Roma.
To refute the speculation though, Shakespeare has revealed that the club have not received any bid for Mahrez as of yet and added that the winger is resuming training as normal with the rest of the squad.
Shakespeare said: "I think Riyad stated his position really clearly. Mine is really simple. While he's here and while we've had no bids officially – it's all speculation.
"He has to be committed to the football club. I have to say in his two weeks back in training, he has been totally committed and he's trained really well.
"Outgoings are inevitable at any football club but until you actually get bids for your players, there is no decision to make."
