The Ecuador international suffered an ankle injury in a Europa League qualifier and made just two Premier League appearances on his return until suffering a further setback.
He was given permission to return to Ecuador and be beside his family during his recovery, yet the Hammers have now called him back to England as he nears a return to fitness.
Speaking to Radio Area Deportiva in his home country, Valencia claims he will be back in training soon and pushing for a return to the Hammers first team.
“I will be back training soon. I’ve been in Ecuador but I was told to be back in England on Saturday. I have the feeling that I will be back playing by New Year — or even sooner than that,” he said.
“It was a shame [to suffer the injury setback]. It’s hard for me, but I have to keep positive and be focused in my recovery because I want be back playing for West Ham as soon as possible.”
Valencia has been a big miss for the Hammers this season, especially now that Dimitri Payet is injured and the team lacks a bit of creativity and prolificacy in the final third.
The former Pachuca ace had a solid debut season in East London, scoring four goals and adding a further three assists, despite being deployed mainly in a wide forward role.
The 26-year-old provides width, direct running and plenty of power in the final third and his expected return around the New Year will be like a new signing for boss Slaven Bilic.
