Barcelona had been linked with Antoine Griezmann before signing Philippe Coutinho, but reports now suggest there may not be room for both players.
Manchester United have also been linked with the Atletico Madrid star and may now be the favourites for the £88million attacker if Barca do end up cooling their interest.
In a huge potential blow to Liverpool, reports have suggested that Coutinho’s arrival at the Nou Camp could spark Real Madrid into swooping for Mohamed Salah as a response.
The Spanish giants would love a world class attacker like the Egypt international, and his departure could of course then prompt Liverpool to sign not one, but two attacking players, so potentially Lemar and Mahrez, leaving Arsenal in a difficult position.
Another option for Arsenal could be Crystal Palace winger Wilfried Zaha, who has been linked with a host of top clubs.
Manchester City may also be an option for the Ivory Coast international, if Pep Guardiola somehow ends up missing out on Sanchez this January.
