Swansea City are on the verge of pulling off one of the signings of the summer by taking Renato Sanches, the prodigiously talented Portugal international, on a season-long loan from Bayern Munich. Talks between Swansea and Bayern, who paid €35m for Sanches last summer, are at an advanced stage and the Welsh club are quietly confident that an agreement is close.

The signing would be an incredible coup for Swansea and owes much to Paul Clement’s contacts at Bayern, where he worked as Carlo Ancelotti’s No2 before taking over at the Liberty Stadium in January. Clement knows Sanches from that period, having coached him for six months, and he encouraged Swansea to explore the possibility of signing the midfielder once it became clear that there could be a window of opportunity.

Swansea were realistic about their chances at the outset and accepted bigger clubs would be interested in Sanches, who was a target for Manchester United before joining Bayern, but Clement’s influence has been a key factor in getting the deal so far down the line. The Swansea head coach has spoken about utilising his contacts across Europe to try to bring in players and he retains close links with not only Ancelotti but other senior staff at Bayern.

Discussions between Swansea, Bayern and Sanches’s agent, Jorge Mendes, have gathered pace over the past 24 hours, turning what had seemed like an ambitious punt initially into a realistic prospect. It is understood the loan fee could be as high as €6m (£5.5m), although Swansea will regard that as money well spent to have a player with Sanches’s ability in their squad.
