Sporting forward Rodolph Douala says that he decided to stay at the club after talking with coach Paulo Bento, but admits Middlesbrough's offer was not good enough for him to move.
The Cameroon international looked certain to join Premiership side Boro as he became unhappy with his lack of first team football in Lisbon.
However, no deal materialised and he now says he is fully committed to life at the Jose Alvalade.
Douala says that his talk with the coach helped him to stay, but admits that Boro did not offer him the right deal to persuade him to move.
"I decided to stay after speaking with Paulo Bento," Douala told O Jogo.
"The truth is that I wanted to play more and there were several months when I thought about changing clubs.
"However, I ended up speaking with the coach and I decided to stay. On the other hand the offers that I received did also not meet with what I wanted."
Douala says that Bento told him he was still in his plans for the future and the player insists he can now give his all for Sporting.
"He told me that he likes me as a player and he understood why I had the desire to leave.
"I want to play, and last season that did not happen, especially after I returned from the African Cup of Nations, but I know that I can give more to Sporting.
"I am very well here and I only think of Sporting in my head. But I do not imagine going to another club now, I am going to earn a place here."
