Graeme Souness is backing Jose Mourinho's appointment at Tottenham to prove a success.
Mourinho has penned a three-and-a-half-year deal in north London after Spurs sacked Mauricio Pochettino on Tuesday night.
“Deep inside he is an angry and frustrated man with the way it turned out for him at United, Spurs will reap the benefit of that," Souness said.
“Will they win the league this year? No. But they will be far more difficult to play against.
“He talks common sense at that is basically what football is about. Off-camera he is jovially funny, he is engaging, extremely knowledgeable and desperate to get back into football.
"He will know where he could have done better and decisions he made he wishes he hadn't made. Spurs will reap the benefit of that big time."
