Manchester United are reportedly preparing a summer move for Atletico Madrid midfielder Saul Niguez.
The 20-year-old has been with Atletico since 2008, but has only broken into the first team this season after spending the 2013-14 campaign on loan at Rayo Vallecano.
Saul's performances have been of a high level this term, and he has emerged into a key player for the Spanish champions despite his youthful age.
According to The Sun, United sent scouts to watch the midfielder in Champions League action against Bayer Leverkusen last week.
While Atletico are desperate to keep Saul, he has a release clause in the region of £18m, which United are believed to be prepared to pay.
