Reports have claimed that Swansea are mere inches away from completing a deal to bring the Icelandic international to the Liberty Stadium on a permanent basis but sources have suggested that Sunderland are planning a late raid on the playmaker’s signature.
Sigurdsson came to the Swans on a six-month loan deal in January of this year after falling out of favour at parent club Hoffenheim.
The midfielder quickly returned to his best and showcased the kind of form that earned him such considerable plaudits during his time at Reading.
Sigurdsson went on to finish the campaign with seven goals and six assists in just 16 starts for the Premier League outfit, becoming an integral member of Brendan Rodgers’ setup.
With reports coming in that Stephane Sessegnon is on the radar of a host of European clubs, Sunderland appear keen to fill the void in attacking midfield in what has been a vital player for them this season.
There will be considerable opposition for Sigurdsson’s signature however, with sides as big as Manchester United being linked with a move for the attacker.
The 22 year-old isn’t the only name on the Black Cats’ shortlist however, as Martin O’Neill is reportedly stepping up his interest in Steven Fletcher.
The Scot seems likely to abandon the Wolves ship in the coming months after seeing the West Midlands side relegated to the Championship.
The 25 year-old managed to score 12 goals for Wolves last season and with Nicklas Bendtner and Asamoah Gyan both departing the Stadium of Light, striking reinforcements will be necessary.
Should either play leave their respective clubs, they would both be expected to command values of around £7.5m.
Sunderland will need to move quickly however, with reports saying that Swansea may have already agreed a transfer fee with Hoffenheim.
