​Barcelona are expected to learn the severity of Ousmane Dembélé's latest injury on Thursday, which could lead to them pursuing a new forward as soon as possible.

The Frenchman has gone down with a hamstring tear and could miss the remainder of the season. If he is to be sidelined for at least five months, Barcelona hope to be ​granted special permission to sign an emergency replacement outside of the transfer window.

According to ​Mundo Deportivo, the results of the tests on ​Dembélé's injury will come back on Thursday, and if things are as bad as first feared, then the club will seek permission to sign a new player as soon as possible.

If they are permitted to do so, it is suggested that the Royal Spanish Football Federation could restrict ​Barcelona to only signing players from ​La Liga or even simply players who are currently without a club.

If they are allowed to pursue a traditional transfer, then Alavés forward Lucas Pérez is thought to be seen as an option.

The former ​West Ham United man has a release clause of €15m in his contract, and it is thought that he would be open to a move to Camp Nou after struggling for minutes this season.

However, Pérez is not alone on Barcelona's radar. ​Marca note that Girona's Cristhian Stuani and Real Sociedad's Willian José are being considered, but the favourite could be Getafé forward Ángel Rodríguez.

The 32-year-old has managed nine goals this season, and his €10m release clause means Barcelona would have no problem signing him if needs be.

Having said that, ​Deportes Cuatro believe 33-year-old Stuani (release clause of €20m) is the favourite ahead of Ángel, so it seems as though Barcelona are yet to make their mind up just yet.

With striker ​Luis Suárez sidelined with his own injury, Barcelona have struggled for numbers in attack in recent weeks. Antoine Griezmann and ​Lionel Messi are the club's only two senior forwards, along with 17-year-old Ansu Fati.
