Former Tottenham midfielder Jermaine Jenas says Manchester United blundered appointing Ole Gunnar Solskjaer.
Solskjaer, who scored United's winner in the 1999 Champions League final, replaced Jose Mourinho in December, initially for the rest of the season.
He won 10 of his first 11 games and was appointed permanently in March, but has lost five of his past seven matches.
Asked about Solskjaer being named manager, Jenas told BBC Sport: "I felt it was all emotional with Ole.
"I felt it was an emotional decision and in any business it should be a thought-out logical decision for the long term.
"One of the things they need to get away from is 'the Manchester United way' and 'that's not the way they used to do it'. What Sir Alex Ferguson did was very unique and United have found it very difficult to replicate with some of the best managers in the world."
