The 25-year-old has been suffering with a toe injury of late, but he is back in training and set to return to competitive action sooner rather than later.
“Of course I am desperate to get back on the pitch with my teammates to help out the squad,” Valencia told West Ham’s official website.
“We know the end of the season is going to be tough, so we all need to be there and do our best for West Ham.
“Right now I’m only thinking about West Ham because it’s approaching the end of the season and we have tough games.
“I’m concentrating on playing for West Ham and if, after the season, they call me for the national team then it will be a great summer.”
Valencia joined London outfit West Ham from Pachuca in the summer of 2014 and has established himself as a key player for Sam Allardyce’s team.
The Ecuador international has scored four goals and created 11 chances in 25 Premier League appearances so far this season, while having a pass accuracy of 76% and a shot accuracy of 45%.
If Valencia can make a swift return and regain the form he showed in the opening stages of the 2014-15 Premier League season, then there is every possibility that he will be called up to the Ecuador squad for the 2015 Copa America.
