Fotospor report Besiktas are interested in Watford left-back Pervis Estupinan, who’s currently on loan at Osasuna.

The Ecuadorian defender has been in impressive form for the Spanish side this season, racking up five assists and one goal in 29 appearances since joining last summer.

It’s reported the Turkish side could make a loan offer for the 22 year old as they see him as an ideal replacement for Caner Erkin. The Turkey international will exit the Super Lig side this summer when his contract expires.

However, the competition is thought to be high for Estupinan, with claims suggesting the likes of Barcelona, Manchester United and Tottenham Hotspur are all interested in signing him.

Estupinan’s loan contract with Osasuna will expire at the end of June 2021, but there were reports in the Spanish media last month that Watford have the option to call him back this summer.

He joined the Hornets in 2016 but has yet to play for the club.
