Barcelona are not ready to negotiate the departure of Marc-Andre ter Stegen for anything below his €80m (£63.4m, $91.1m) release clause, according to Sport. The Spanish publication claims sources at the Catalan club have insisted the German international is "not for sale", following ongoing speculation linking him with a summer move to Manchester City.

The Telegraph reported on Thursday (31 March) that the future side of Pep Guardiola are on the verge of clinching an agreement with Barcelona to sign the custodian, beating off interest from Liverpool, in a deal worth around £20m.

The news came just days after Ter Stegen opened the door to a summer move after growing frustrated with Luis Enrique's rotation policy between the sticks, with him playing in the Champions League and the Copa del Rey but serving as Claudio Bravo's back-up in La Liga.

The Barcelona keeper told sport1.de while international duty: "Barca are a great club and things can still change between now and the summer. If the situation remains the way it is at the moment, however, then we're definitely going to have to talk – there's no avoiding that."

Sport, however, claims that "sources at Barcelona" have assured that the club are not going to negotiate his departure at any price, although they are aware about the Premier League giants' interest in securing his services.

This would mean the only option for City or Liverpool to secure the services of the 23-year-old is to meet his €80m release clause in full, as he is under contract with the La Liga outfit until 2019.

The Catalan-based publication says Barcelona consider Ter Stegen their goalkeeper for the next decade, as Bravo is already 32-year-old. However, if the keeper has different plans and wants to leave the club, he will need to convince another team to pay his release clause.

Sport adds that Ter Stegen, who already speaks fluent Spanish, is happy in Barcelona and that his girlfriend has started to study architecture at the local university.

Ter Stegen, meanwhile, has appeared to confirm this by posting a picture on Twitter of his return to Barcelona after the international break with the message: "Home Sweet Home".
