Thought this was an interesting article on how Martinez is using Deulofeu

It works like this. Martinez is deploying the 21-year-old Deulofeu in a very wide role on the Everton right, telling him to get that touchline white paint on his boots and to stay out there. By hugging that flank and proving his ability to deliver crosses and passes with unerring accuracy, he is causing distinct problems for opposition sides.
The main one is the horrendous difficulty the opposition left-back faces when the ball is coming into the area from the opposite flank to the one he and Deulofeu occupy. The left-back absolutely must venture into the centre of defence at that moment, to help cover for the defenders who head out to meet the left-sided advance. If the left-back stays out wide with Deulofeu, there will be big holes in the centre. But it is a horrible situation because he knows he is leaving Deulofeu unmarked and able to get a run on him if Everton switch play at pace.
And, boy, are the side proving capable of doing that. Of course, a ball moves faster than a man, so once that switch is made, the defence is in trouble. One example was in the exciting 3-2 win at West Bromwich, where Chris Brunt, a good defender, was stuck between the devil and the deep blue sea in this respect.

The partnership is particularly marked at Goodison Park, where in four home games when Deulofeu hasn’t played, Lukaku hasn’t scored. In four homes
games when he has played, Lukaku has scored.
The average position charts show the two ways Everton have worked it. The first shows the positions from the Watford home
game on the opening day of the season: the full-backs, Brendan Galloway and Seamus Coleman, are the only ones providing the width but Lukaku and Kevin Mirallas are both operating in a similar central area and it’s all very narrow. Deulofeu didn’t play. The second for the 6-2 home win over Sunderland shows Deulofeu getting that width and the Sunderland average position chart reveals just how isolated their left-back was.
There’s an element of gambling in the way the Spaniard is being used. Martinez is quite obviously saying to him: “Stay up there sometimes. You don’t have to track back every time.” If I were Coleman I’d probably have something to say about that, with all the extra work it’s creating! But though it can be risky, it also plays into Everton’s hands. The opposition left-back bombs on and with Everton willing to use the 20-yard pass when they turn over possession that opposition defender is often unable to get back in time when the ball finds Deulofeu.
Everton are flying when that happens, because the defensive midfielder has to come out to meet the danger and try to head it off, leaving space in the centre of midfield that Ross Barkley can move into and capitalise on. Another beneficiary of that extra space is Arouna Koné, who generally operates on the left of the line of three behind Lukaku but likes to come and play narrow, too.
