Alex Neil insists Norwich City must keep their heads on a frenetic transfer deadline day.

The Canaries' boss has until 11pm on Wednesday to fine tune his squad for the Championship promotion push after the club confirmed on Tuesday new Portuguese striker Nelson Oliveira was on board following his move from Benfica for an undisclosed fee.

Neil is keen to recruit another forward, with Dieumerci Mbokani and Dame N'Doye are on his radar, while the likes of Crystal Palace's Fraizer Campbell and West Ham's Enner Valencia could also be final day targets in the scramble to attract fresh firepower.

Young French defender Jérôme Onguéné has been heavily touted with a Carrow Road summer switch after recent talks in Norfolk and the Scot must also decide on the futures of some of his fringe men, with Kyle Lafferty strongly linked to Cardiff City.

Neil is ready for what lies ahead over the remaining hours of what he predicts will be a busy finale across the top-end of the professional game.

'Anything is capable of happening in this window,' he said. 'I think there will be a lot of movement, a lot of money spent and a lot who feel they need to do this or that and will overspend as a result. Why does that happen? It is really simple. When you have assets at your club at the start of the window you have a price in mind that is extremely high normally, because you deem what you have got to be of a certain value.

'A club who wants to buy a player may have a lesser value and they know sometimes a selling club needs to offload players, so the value is likely to come down. The opposite happens when a club perhaps picks up an injury or two in a key area of the squad and they need to spend and other teams know they are going to over-spend to compensate for that. That is the main crux to why things get done right at the end.'
