John Mensah staying at Sunderland beyond his one-year loan period is by no means certain after Steve Bruce revealed the defender’s many injuries is playing on his mind.The deputy Black Stars captain’s quality is no doubt according to Bruce, but the Sunderland manager is not certain about his fitness following a series of injuries.“There is ten million quids worth of player there. It’s a very difficult decision for me. I know we are a better team when he is on the pitch. He is a top, top player, as we saw at Arsenal last week.“We will look at it in the future. At the moment we’re just trying to get a win so I’m not focusing on that. Make no mistake, we will have a conversation with Lyon over the next few weeks. Another loan deal? Possibly,” Bruce said.Bruce called Mensah's playing record awful and says Sunderland will speak to Lyon when the time is right.“If you look at John, his playing record is awful. He had a great spell at Rennes before he got his big move to Lyon. But he got injured at Lyon and they bought someone else.“We’ll speak to Lyon when the time is right. It’s like a Paul McGrath (at Manchester United) situation. He can’t train at the level you want him to train and we have to be careful with him.”Source: Kickoff.com
