Fulham and Swansea City have reportedly agreed a fee in the region of £20m for defender Alfie Mawson.
The 24-year-old, who played for England at Under-21 level, made more than 70 appearances for the Swans following his switch from Barnsley for £5m in 2016.
Mawson featured in all of Swansea's Premier League games last season but could not prevent their relegation to the Championship.
The former Brentford trainee has been linked with a number of top-flight clubs this summer and, according to Sky Sports News, the promoted Cottagers have edged closer to securing his signature ahead of Burnley and West Ham United.
Mawson still has two years remaining on his contract at the Liberty Stadium.
