The Telegraph exclusively reports that Manchester United will review Ten Hag's qualifications and dressing room relationships before making a final decision on the Dutchman's future before the end of the season.
Manchester United's FA Cup semi-final against Coventry City has raised new questions among United fans about Ten Hag's suitability for the job.
United will carry out a detailed assessment of Ten Hag's strengths and weaknesses and his relationship with the team in order to determine whether his approach suits the team's general style or whether a change of manager is necessary.
What happened in front of United's new boss Ratcliffe on Sunday did not bring Ten Hag any good, and the situation could become untenable if United were to be completely disqualified from Europe.
United's new technology director, Wilcox, appointed last week, will be keeping a close eye on Ten Hag's training in the coming weeks. During his analysis, he will also have extensive meetings with head coaches, staff and players.
Manchester United are keeping a close eye on whether Ten Hag's relationship with the dressing room has broken down. A number of United players in the squad, including Jadon Sancho, Marcus Rashford and more recently Garnacho, have clashed with Ten Hag this season.
Manchester United will look into whether this season's woes have been largely due to injuries and personnel factors, or whether there are deeper issues such as players ignoring instructions, or inflexibility and intransigence on the part of the coach.
If it's the latter, United want to know if Ten Hag is too stubborn or if he can accept a tactical change.
The Old Trafford hierarchy are aware that Ten Hag's future must be decided before the end of the season, with United's final Premier League game away to Brighton on 19 May, while the FA Cup final against Manchester City will be played at Wembley Stadium six days later.
