Valencia has 19 caps and four goals for Ecuador

The 21-year-old winger, who has been impressive during a year-long loan spell at the JJB Stadium, has agreed a three-and-a-half-year contract.

And Wigan boss Steve Bruce is delighted to have secured his services.

"He has pace, trickery, he is as strong as an ox and has a great work ethic," he said of his fourth January signing.

Valencia joins defenders Maynor Figueroa and Erik Edman, and striker Wilson Palacios as Bruce continues his squad strengthening.

The Latics manager said one of his main priorities was to ensure Valencia, who has featured in every match since he took over Wigan in November, was a permanent fixture at the club.

"Now that his future is sorted out, I want him to focus completely on his football and keep improving because I believe he has the potential to be a top, top player," Bruce said.

Valencia has made 35 appearances for Wigan since the start of last season, scoring one goal.

And the South American cited Bruce's influence and the fans for his recent run of good performances.

"You can see how the team is motivated now and I think he (Bruce) will be successful here in the seasons to come," said Valencia, who has 19 caps for Ecuador.
