My Predicted United Line-up:
Despite a poor result at the weekend I don't think there will be many changes. Matt Smith grabbed a goal at the weekend but personally I wouldn't start with him away at a Premiership side with the ability that Newcastle have. I wouldn't start with Byram either with him just coming back from injury at last, I wouldn't risk him in a game like this. Especially not with another important League game at the weekend to come against Millwall.
It would be nice to see Alex Mowatt involved after an impressive showing in the previous round at Doncaster but who knows what Brian McDermott is thinking. Only time will tell.
