The 27-year-old has been strongly linked with a January move to Chelsea.
Tamas’ British agent, Jon Kirtland, told the Birmingham Mail: “I’ve spoken to Gabriel and what has been written about him is simply not true.
“People have noticed that Chelsea have injury problems, realised that Robbie Di Matteo is an ex-Chelsea player and decided to put two and two together only to get 10.
“Gabriel doesn’t like speaking to the Romanian press because he’s had problems before.
“They asked him for an interview and he replied that he would speak to them at the end of the season. The next thing he sees are these stories.
“I can promise 100 per cent that there is nothing in these stories. Chelsea and West Brom have not had any contact that we’re aware of and we certainly haven’t.
“He is happy at West Bromwich Albion, he loves playing for Robbie Di Matteo, with whom he has a great relationship, and he wants to help the club establish themselves in the Premier League.
“Gabby has a lot of clubs on his CV and it’s always been his intention to stay at West Brom for a while.”
