According to Wales Online, Swansea City centre-back Alfie Mawson is on the radar of Premier League trio Watford, West Ham and Everton, while Scottish giants Celtic are also keen on the 23-year-old.
The Hammers are said to be preparing a £25million bid for the services of the England youth international who was also being monitored by Tottenham at a time.
Manager David Moyes wants defensive reinforcements as he attempts to help West Ham retain their topflight status after a messy start to the campaign, and Mawson is top of his wish list.
The Toffees are also keen on the highly-rated youngster, as boss Sam Allardyce wants to prevent his side from leaking cheap goals on a regular.
Celtic only recently brought in Marvin Compper from RB Leipzig, but are still looking for one more centre-back, with manager Brendan Rodgers keen on Mawson.
With relegation staring them right in the face, Swansea are not ready to lose their man for any price, and are already planning on handing him a renewed and improved contract as they look to stave off interest.
With the chasing quartet all hot on their heels, though, it remains to be seen if Mawson will be at the Liberty Stadium come February.
