Diego Leon is set to undergo a medical ahead of a move to Manchester United.

United scouted Leon and Cerro Porteno have claimed a package of around £6million has been agreed for the defender, who has impressed for his club in Paraguay's domestic league.

Leon has touched down in Manchester to finalise his move and will undergo a medical at Carrington, although he won't officially start playing for United until the summer.

United have arranged a pre-contract agreement with the 17-year-old and his transfer will consequently be lower key than a senior player arrival, but Leon will still get the opportunity to meet staff and will be given a tour of the facilities at Carrington during his trip to Manchester.

It's understood technical director Jason Wilcox has played a key role in the deal to sign Leon, and United could look to explore more deals in the South American market in the next few years.

Leon is a natural left-back, which has become a problem position for United in the last two seasons due to Luke Shaw and Tyrell Malacia being unavailable for large periods of time.

United are still expected to sign a senior left-back in the summer because Leon is a young talent. The youngster will need time to develop and so patience will be needed while he settles in England.

Sekou Kone, who is 18 years old, signed from Malian club Guidars FC last August and sources have reiterated he will need time to get to grips with the demands of English football.

Kone has made just one start for the Under-21s this season and he picked up a small issue in that game against Huddersfield Town in November, in which he lasted 40 minutes.

Leon and Kone are both seen as high potential young players who should progress to the first team.
