Leroy Fer is determined to prove his doubters wrong after his hopes of a return to the Premier League were dashed, according to QPR boss Chris Ramsey.
Sunderland and West Ham were keen on the Netherlands midfielder, who has a knee problem.
But the Black Cats subsequently pulled out of a deal to sign Fer, 25, on a season-long loan following a medical.
Amid doubts about his long-term fitness, Fer is now expected to stay at Rangers – and Ramsey believes the player can make a major impact in the Championship once he returns to action.
Fer is also still hoping to secure a place in his country’s squad for the European Championships next summer.
Ramsey said: “I think he’s got the bit between his teeth to prove a lot of people wrong about his injury and prove people wrong about his form, because he wants to be involved with the national team as well at the end of the season.
“I think he knows that the QPR fans are behind him and he owes them for their support. I’m very excited about the way he’s conducted himself around the place.
“He’s given us his word that he’s fully committed to the club and that he wants to see us climbing up the table.
“He’s a big miss for us because he’s a very good player and his attitude has been fantastic.”
Ramsey says he is confident Fer will be able to handle the rough and tumble of the Championship as relegated Rangers battle it out in the second tier.
And he wants the former Norwich player to have a leading role in the dressing room as well.
“Obviously he’s a talented player, but he’s now got a chance to show his resilience and whether he can help other players,” Ramsey explained.
“There’s quite a few young players in the squad and he’s more experienced and needs to really show some leadership.”
