West Ham United manager Slaven Bilic
The Hammers will be looking to heavily invest in their playing squad this summer, after last year's disastrous recruitment drive proved costly in their ability to challenge for the Europa League spots this term.
West Ham's owners must spend in a manner befitting of a club who genuinely want to force their way inside the band of Europe's elite, and that will mean potentially breaking their transfer record, on more than one occasion.
And an ideal signing for Slaven Bilic in the summer would be Arsenal's Theo Walcott.
Whilst the Croatian has plenty of attacking options at his disposal, one attribute his forwards lack is pace, and the 27-year-old Gunners star would bring that in abundance.
Walcott has actually enjoyed one of his better seasons for Arsene Wenger's men this season, scoring 16 goals in 28 appearances, but with so many attacking options available to the Frenchman at the Emirates, the speedy forward's place in the team will never be guaranteed.

A move to West Ham would see him become a first-team regular - something that would increase his chances of being picked for the England national team.
And with Walcott down the right-wing, Robert Snodgrass on the left, and Manuel Lanzini in behind Andy Carroll, the Hammers would arguably have one of the most dangerous group of attacking players in the league.
Walcott's contract with Arsenal does not expire until the summer of 2019, so a transfer fee in excess of £25 million will surely be required to prise him away from the Emirates, but it is that kind of money that West Ham have to start spending if they are to make serious progress.
