Sigurdsson, 27, scored nine goals last season and teamed with Fernando Llorente to form a potent duo. He’s recorded seven-, 11-, and 9-goal Premier League seasons for Swans.

It’s a huge hit to Swans’ hope of surviving another season in the Premier League should the Welsh side not invest in a replacement. That said, using a good portion of that money would arguably make Swansea superior to their pre-sale status.
The move may also finally tip the scales for Everton in accepting an offer for Ross Barkley.
Swansea saw Sigurdsson score seven goals in 18 appearances during a loan from Hoffenheim in 2012, only to see the Bundesliga outfit sell him to Spurs for just under $12 million.
Swans then purchased Sigurdsson two years later for $12 million, and have now made $46 million on midfielder.
