Teenage star spotted at airport ahead of Manchester United medical tomorrow

Diego León has been spotted at an international airport ahead of his visit to Manchester United in the coming days.

The 17-year-old is set to become United's first signing of the calendar year when he signs from Paraguayan club Cerro Porteño, though he won't be able to officially join until he turns 18 in April.

Manchester World revealed earlier this week León would visit the club's Carrington training ground early next week, where he will undergo initial medical examinations and meet club staff ahead of his proposed transfer at the end of the season.

León was seen at Silvio Pettirossi International in Luque, Paraguay, on Saturday before he flew to Europe for a 'few days' in Manchester. It is understood the teenage full-back will spend two full days with the club before he is due back for international duty with the Paraguay U20 squad for the South American Championship in Venezuela.

The provisional deal has already been sealed by technical director Jason Wilcox, with lead South American scout Giuseppe Antonaccio credited as the one who pushed for the move. United have identified South America as an untapped market for potential bargain buys and will continue to monitor the continent for future youth recruits. Although viewed as a first-team signing, the teenage full-back could be given time in the youth setup to settle in his new environment, just as Sekou Kone has since he joined last summer.
