Alex Neil is wary of his Norwich City squad running out of gas over the Championship run-in.

The City boss felt the club's recent heavy workload was a major factor in the midweek defeat to Wigan.

Neil made three changes to his starting line up for the Latics after a gruelling derby win over Ipswich, but City's efforts at Carrow Road lacked the energy and urgency of late.

'I freshened the team up and made three changes and put guys in who I felt had a point to prove if you like, hoping they would go on and show me that they deserved and merited a place in the team,' he said. 'But the guys who had been playing didn't hit their levels either. Even when Wes (Hoolahan) went on you could see how tired he was and it was the right decision not to play him from the start. I spoke to him after the game and he said he felt tired, as did quite a few of them, so we haven't done much in terms of activity since the Wigan game.

'Once we get Millwall out of the way we have a free week before the next match and we can tone it down and let them recover and prepare for the next batch of games. The fact is when you go midweek to weekend in such a short period of time it can be intense, but the adrenaline and the pride that has been damaged will get them through (at Millwall). There won't be any issues with that.

'I think we looked fatigued and tired the other night. When I first came down I made it clear how hard I wanted my team to work but six games in the space of just over two weeks really took its toll. It is not an easy thing to do, particularly to change it around in a short period of time.'
