Swansea City chairman Huw Jenkins believes Bafetimbi Gomis will have a strong end to the season following the French striker's decision to stay.
Gomis has been linked with a move, and the Swans rejected a bid from West Ham.
The 29-year-old committed his future to Swansea on Twitter, writing: "I have decided to stay with Swansea... It's the best choice for me."
Jenkins said: "I can only see him having a great end to the season for us."
He added: "There's always going to be a lot of interest in players like Gomis because he's a talented player and he scores goals.
"I think now he's got a chance to play games and get minutes on the pitch in the Premier League to show what he can do, it's a big thing."
Gomis had cast doubt over his future at Swansea when he suggested in an interview with a French television channel that he could leave.
The Swans had maintained they wanted to keep the French international striker following the club-record sale of top-scorer Wilfried Bony to Manchester City.
And Gomis, who joined Swansea from Lyon in June 2014, has now publically declared his intention to stay.
"Even if I was sad before because I didn't play a lot. Now everything is different. I believe in this team and his project," Gomis wrote on Twitter.
"I have spoken with the coach and I have his confidence and he has mine. I am lucky to play and live to Swansea."
Swansea left-back Neil Taylor has also been the subject of transfer speculation, with Crystal Palace and West Brom interested in the Wales player.
But Jenkins is confident the former Wrexham man will stay at Liberty Stadium.
"I spoke to Neil last week, and Neil Taylor does not want to go anywhere," he told BBC Radio Wales Sport.
"There's always going to be speculation but you want your best players to stay and Neil is one of them."
Taylor's future had been in doubt with Swansea enquiring about the possibility of signing Norwich left-back Martin Olsson.
But Jenkins says that deal looks unlikely now.
"We couldn't quite agree with Norwich," he added.
"We are not in a position where we need to panic or chase them [players].
"It's a good way to work as we can wait for the next transfer window."
