Michael Keane is on Manchester United's radar ahead of Jose Mourinho's summer rebuild but they face the prospect of losing out to Liverpool, sources have told ESPN FC.
Keane has impressed enough for Burnley this season for Mourinho to ask United to monitor the defender's situation.
The 24-year-old, who made his England debut in March, is expected to leave Turf Moor at the end of the season, and United are in the running to bring back a player who left Old Trafford permanently in 2015.
