Several clubs have inquired about the Turkey captain but there are no formal offers currently under consideration, although Gareth Southgate still expects him to leave before the transfer deadline at the end of the month.
However, the 27-year-old underlined his commitment to the cause with a lively cameo appearance capped by the final goal in Saturday's 3-0 win at Swansea.
Tuncay: "It was very nice of the fans to sing my name like that (at Swansea).
"It means a lot to me.
"It was good to score and as long as I'm here I will do my best for Middlesbrough.
"I don't know what is happening yet with other clubs."
Southgate: "The most important issue is the team spirit. If I didn't feel he was going to give everything then I wouldn't involve him.
"He wants to play football and it would be foolish not to pick him while he's here.
"His approach and attitude is right and he's a class act.
"Tuncay was unfortunate in that he had tonsillitis for the first game and that raised questions outside the club, but he was genuinely disappointed that he couldn't play."
