Neil Warnock has claimed Erik ten Hag will not last at Man United and his expensive summer signings would not have started for Huddersfield when he managed them.
Sunday's 3-0 loss to Manchester City was United's seventh in 14 games this season, and it has turned up the heat on Ten Hag again following three straight wins.
The Manchester side will meet Newcastle in the Carabao Cup at Old Trafford tonight in a repeat of last season's final, and the Dutchman will be hoping for an immediate response.
However, former Cardiff City and QPR manager Warnock believes his days at the club are numbered.
