United’s dismal end to the season – with just two wins in their final 12 games in all competitions – has seen them miss out on a place in next season’s Champions League.
Their early resurgence under Ole Gunnar Solskjaer has fallen flat, and Mourinho insists the same problems he encountered earlier in the season remain.
“About Manchester United, I want to say only two things,” Mourinho said.
“One is that time has spoken. Two is that the problems are still there.
“Was I a victim of [Paul] Pogba? No.
“The problems are there, you can imagine that the problems are the players, the organisation, the ambition, I only say that I can not say yes when you ask if Paul was the only one responsible.”
