Manchester United are monitoring Leicester midfielder James Maddison but face competition from a number of their Premier League rivals, sources have told ESPN FC.
United have expressed an interest in the 22-year-old, along with Manchester City, Chelsea and Tottenham, but have not submitted a formal offer.
- When does the transfer window close?
Leicester are under no pressure to sell the England under-21 international, who has only spent one season at the King Power Stadium, and would demand a large fee before allowing him to leave.
Maddison scored seven goals in 33 appearances for Leicester last season following a £20 million move from Norwich 12 months ago.
His performances earned him a call-up to the senior England squad in October but he will represent the U21s at the European Championships this summer. In a warm-up game between the U21s and Gareth Southgate's full squad at St George's Park last week, Maddison was one of the stand-out players.
United manager Ole Gunnar Solskjaer is looking at a number of promising British players as part of his Old Trafford rebuild.
Wales winger Dan James, 21, is expected to arrive from Swansea after the international fixtures and there is also interest in Crystal Palace full-back Aaron Wan-Bissaka, 21, and Newcastle midfielder Sean Longstaff, 21.
Leicester, who are preparing for their first full season under manager Brendan Rodgers, are keen to keep hold of Maddison as well as another prize asset, Harry Maguire.
They were able to price United out of a move for Maguire last summer and are confident of doing the same again with Maddison, who is under contract until 2023.
The attacking midfielder, who was playing League One football for Coventry five years ago, could command a fee of more than £50 million if he is sold this summer.
