Lyon president Jean-Michel Aulas has confirmed that striker Alexandre Lacazette is for sale and could leave the club this summer.
The £50million striker was all set to join Atletico de Madrid before the Court of Arbitration for Sport upheld the transfer ban imposed on the Spanish giants.
Manchester United have now entered the race and are strong favourites to secure the services of the Frenchman.
"Real and Barca [previously] saw their [transfer] punishment reduced with a favourable decision, it wasn't the case for Atletico," Aulas said.
"It's good and bad news. It was, in financial terms, a very significant operation. Of course that has changed everything.
"We had given Alex the green light to go to Atletico, the club of his heart. I've not had his agent on the phone, nor him, as I've been in Cardiff, but I had said to Alexandre not to get too far ahead of himself, as there can always be disappointments in football.
"It brings into question the commitments made on both sides. We had made progress on possible solutions. We might have one extra striker next season."
