Ferdinand says United can't allow Barcelona to dictate the pace of tonight's game if they are to have any chance of progressing into the Champions League semi-finals
“I think he (Ole Gunnar Solskjaer) has to make sure they're tight at the back, the first 15 minutes they wouldn't want a repeat of that (the first leg)," Ferdinand told BT Sport. “They looked nervy, they looked on edge a little bit in the first 15 minutes and that's when Barca were turning the screw.
“If they can come out and be on the front foot and change the pace of the game, I think Barca are used to playing at their own pace, if they can change the pace of the game and put them under a bit of pressure then we're going to get a couple of chances hopefully and we'll put them away.
“My heart says yes they can (qualify) but I think it's more about what Messi turns up, he's that great and done so much at a top level for a consistent period of time. It could be 1-0 Man United and then we go penalties."
