Sanches joined the Bundesliga champions from Benfica last summer, following an impressive showing at Euro 2016 for Portugal.
However, the 20-year-old failed to live up to his £27 million price tag at the Allianz Arena as he slipped down the pecking order at Bayern.
And with the Swans desperate to replace the creativity lost through the sale of Gylfi Sigurdsson to Everton, Paul Clement has jumped at the chance to bring Sanches in.
As you’d expect, Swansea fans were absolutely over the moon with the news, reacting in hilarious fashion as the club confirmed the youngster’s arrival:

Sanches made 17 appearances under Carlo Ancelotti last season but struggled to make much an impression in a midfield containing Arturo Vidal and ex-Barcelona star Thiago.
Could he be the key to Swansea’s Premier League survival this year?
