The Mackems have already signed one shot-stopper this month.
Talksport are listing Sunderland as a potential destination for FC Basel goalkeeper Tomas Vaclik.
The Black Cats were previously desperate for cover between the sticks, following an injury to regular shot-stopper Vito Mannone.
But having initially been denied permission to sign Mika from Boavista on transfer deadline day, the Portuguese was eventually granted a move to the Stadium of Light on appeal.
Despite Mika’s arrival at the start of the month, England Under-21 international Jordan Pickford has remained a firm first choice for Sunderland boss David Moyes.
And with Mannone due back around December time, it is unlikely the Premier League strugglers will look for further reinforcements when the winter window opens on 1 January.
This has not stopped Talksport from speculating about Vaclik however, after the Czech international confirmed his desire to move to England’s top flight.
“I love England. I love the culture of the football here and everything around the Premier League – the atmosphere in the stadiums and even out of the stadiums in the cities,” he is quoted as saying.
“Since I was a child I have had a dream to play in the Premier League as I think it is the most difficult league for the goalkeeper. I would like to see if I can play on this level. It would be nice to play here.”
The 27-year-old, who has eight caps for his country, arrived in Switzerland from Sparta Prague in 2014 and is due to face Arsenal at the Emirates on Wednesday.
