On-loan Barnsley striker Chris O'Grady has refused to rule out a permanent switch to Oakwell in the summer.
O'Grady, 27, is currently on loan at Barnsley from npower Championship relegation rivals Sheffield Wednesday until the end of the season.
But the former Leicester man says he will let his football do the talking and the rest will take care of itself.
"I'll definitely assess it at the end of the season, but the infrastructure in the club, well it can't get any better," he told The Star.
"The players couldn't be any more accommodating and the manager (David Flitcroft) is just perfect for me. I'm enjoying it and I'm enjoying my football, which is the most important thing.
"You want to prove that you're a better player than your club believes you are. If I'm not regarded as an important player for the team then you've just got to prove people wrong."
He added: "But if I perform then that [a new deal] will take care of itself."
Sidwell was dismissed for serious foul play during his side's 3-2 home victory over Queens Park Rangers and an Independent Regulatory Commission upheld the red card shown by Phil Dowd.
The player's three-match suspension will commence with immediate effect and rule him out of the trips to Newcastle and Aston Villa as well as the west London derby against former employers Chelsea.
Sidwell was sent off with 12 minutes of the Monday Night Football encounter left for a lunge on Armand Traore, which forced the left-back off eventually.
