Tottenham finished third and second under Mauricio Pochettino, but Carragher believes there is plenty of work to do before the north Londoners can mount another title tilt.
“Tottenham were a team that pressed from the front with energy, who played from the back,” the former Liverpool defender told Sky Sports.
“Those two big things from the Pochettino era are gone now with Jose Mourinho. They don’t press from the front, and when they play out from the back they don’t have any idea what they are actually doing. They just go back to the goalkeeper and he smashes it forward.
“I said that this Tottenham team was gone. It was the end of a cycle with Pochettino, either the players have got to go or Pochettino has got to go. Pochettino went. We know why: because it’s easier to change one man than seven or eight.
“But Pochettino was one or two players away from winning the league. I think Jose Mourinho, the team he’s got now, if he’s wanting to play the way he’s wanting to play – which is not the way these players are used to playing – he needs four or five players just to get back to where Pochettino team was, never mind actually getting to where Tottenham actually want to get: Champions League finals and challenging for the title.
“I think they’re a long away, and I think there will have to be major changes in the summer.”
