Valencia, 27, enjoyed a stunning 2014 World Cup campaign, scoring all three of Ecuador's goals in the competition, and those displays earned him a big-money move to England with West Ham.

The attacker, who can play out wide or up front, impressed with his pace in his first season at West Ham, scoring five goals in 37 games under Sam Allardyce, but he was less of a regular under Slaven Bilic during the 2015-16 campaign.
After five goals in 23 games that season, Valencia was sent out on loan to Everton in August, where he found the net just three time in 23 games, with the Toffees unsurprisingly rejecting the chance to purchase him permanently.

Valencia appears to have no future under Bilic, and Football.London report that the former Pachuca star is set for a return to Mexico, with West Ham ready to sell him to UANL Tigres for just £5million.
That's a huge loss for West Ham, and another example of why team shouldn't just sign players based on their World Cup displays – as the Hammers also found with Mexican winger Pablo Barrera in 2010.

Valencia's move isn't quite so simple though, as the report adds that his former club Pachuca are interested in re-signing him too, and could hijack the deal at the last minute to beat rivals Tigres to the punch.
That would give Bilic a little more money to spend in the transfer market, and get more dead wood out of the London Stadium, having already parted ways with the likes of Alvaro Arbeloa, Gokhan Tore and Havard Nordtveit this summer.
