Norwich City's defence may have failed to shackle Watford's deadly duo, but Everton's prolific striker Romelu Lukaku is in a different class for Alex Neil.

Lukaku has plundered seven goals in his last six games, although Neil insists last week's mauling against Troy Deeney and Odion Ighalo will have no bearing on the Canaries' bid to shackle the Toffees' frontman.

'The two Watford lads play as a pair. That is their strength. If you put one or the other in the side on their own I am not sure how much of an impact they would have, in comparison to Lukaku,' said Neil. 'He is more of an individual but his £28m price tag and the fact Chelsea bought him tells you, you are dealing with a good player.

'He averages one goal every two and although he is 6ft 4in I don't think he has scored that many with his head, maybe three or so, so we have to limit balls into his feet. We dealt with him at their place (in the cup) and hopefully we can repeat that.

'Watford might have a front two but with Everton it is likely to be Lukaku up top on his own with (Arouna) Kone coming in off the left-hand side. That is a key difference and hopefully how we play is different.

'When you get beat and it's not a good performance it takes a day or two to shake it off. Now it's in the past and we have to move on and make sure we are on the front foot in this game.'

Neil may not have to worry about the threat from Everton midfielder and his ex-Hamilton protégé James McCarthy who is struggling with a hip injury.

'I saw him the first time at 15 and automatically I thought, 'wow, he is special',' said Neil. 'I had been involved in the game a long time up to that point and I had never seen a 15-year-old come in and hold their own at a first team training session, but not only that, to stand out. It doesn't surprise me that he has gone on and become a top player.'
