Sunderland are facing competition over the signature of John Mensah after a French top-flight club were rumoured to be interested in his services.
The Ghanaian centre-back moved on loan to the Black Cats at the start of last season with a view to a permanent deal, but injury problems have led to manager Steve Bruce wanting the 27-year-old on a pay-as-you-play deal.
Mensah excelled in Ghana's 1-0 victory over Serbia in their opening game of the World Cup, leading to rumours that an unnamed French side have contacted parent club Lyon about a possible transfer.
It is understood that Mensah would still like to return to the Stadium of Light, however, Bruce is also negotiating a £6million deal for Schalke defender Heiko Westermann and may have to lose the Ghanaian in exchange.
Lyon are thought to not be willing to make a decision over the player until the tournament is over, with Ghana having reached the second round of the finals.
"Yes, there has been an offer for John from a club in France," Mensah's agent Fabien Pivateau told The Journal
"He has played very well in the World Cup and I think that people have noticed what a good player he is again.
"For John and for me, he wants to go back to Sunderland. He loves the people, he loves the atmosphere, he loves the manager and he loves the club. He feels at home at Sunderland.
"But I do not know what will happen and Lyon have other offers now. We will have to wait and see until after the World Cup."
