Owen Hargreaves has warned Ralf Rangnick of his management style with Cristiano Ronaldo following Manchester United's 3-1 win at Brentford on Wednesday night.
With the Red Devils 2-0 in front, Rangnick decided to substitute Ronaldo in the 71st minute - much to the Portuguese superstar's visible frustration.
Rangnick tried to play down the incident post match and that he made the decision based on the 'interests of the team'. However, Hargreaves believes he must keep his former team-mate on side if United are to salvage their disappointing season.
'I don't think Ralf will be taking Cristiano off again any time soon,' the ex-United and England midfielder said in his post-match analysis for Optus Sport.
