Ronald Koeman's Everton reign is yet to begin and it looks like he will start it on the back foot. As transfers struggle to go through and big name players edge towards the exit door, Koeman's rebuilding job at Everton is becoming vaster by the day. Luckily, Koeman is just the man for the job and it's hard to imagine a better managerial appointment for the Toffees this summer.

Having said that, Slaven Bilic and West Ham are also sniffing around for potential signings this summer and there is a real chance that the Toffees and Hammers could clash financially. It would be enticing, as the two sides who are looking to pierce the monopoly of the richest clubs in the English games tussle for big names.

West Ham, however, are likely to have the lure of European football, whilst Everton are facing a battle to keep hold of their best players.

Could the Hammers move to weaken their rivals?

Seamus Coleman

Everton's Irish right-back struggled to find his top form for much of last season, as the Toffees experienced defensive woe throughout the campaign and Coleman's bursting overlaps down the right saw their effectiveness dip.

From being linked with Manchester United a couple of years back, it's hard to envisage any transfer for Coleman over the course of the next couple of seasons. However, such is West Ham's shortage at right-back, Coleman could be the answer to the Mikhail Antonio shaped problem.

Signing Coleman, who could also mentor Sam Byram, to fill the void at right-back would free-up Antonio to play in his more natural forward role.

Gerard Deulofeu

After impressing hugely on-loan at Everton, Deulofeu has been significantly underwhelming since signing for the club permanently and only started 16 matches in the 2015/16 campaign, as Everton fell far short of all expectations and Roberto Martinez was sacked.

Bilic is hardly short of attacking options in his West Ham squad right now, but Deulofeu is a different challenge to defenders. His mazy, direct dribbling makes him a constant challenge to mark and would be a wonderful impact sub for the Irons.

Romelu Lukaku

West Ham's highly-publicised pursuit of a striker is becoming a little tedious. Rebuffed on several occasions, West Ham might want to look a little closer to hope for the big name, reliable, goal-scoring centre-forward that Bilic so desperately craves as he heads in to the difficult second season.

For all his weaknesses, Lukaku would be an astonishing upgrade on any of their current central striking options, having netted 18 times last season.
