Scottish great Graeme Souness has hailed the ruthless approach of Chelsea boss Thomas Tuchel after their defeat of Tottenham on Sunday.

Souness traced back Tuchel's no-nonsense approach to a match last season as a reminder to his team of the standards that need to be maintained.

"He's got the squad where he can mix it up," the Scot said. "Go back to Callum Hudson-Odoi [against Southampton in February].

"Sub goes on, he's not happy with him - get him off. That statement alone has put a marker down for everyone in that dressing room.

"You can't mess with this guy. He's got a squad where he can keep mixing it. I'm as big a fan of Mason Mount as anyone out there, but he felt he wasn't quite at it and I like the way he chats about it not being all about formations and tactics [in his post-match interview].

"For him, it was more about energy levels and being first to the ball and being aggressive and he's picked up very quickly that in our game that's so important, more important in the Premier League than any other league that you have to be physically ready for it.

"If you're a big team, whoever you're playing, you have to be ready to meet that physical challenge head on. It's incessant now.

"We saw with Saul, who he watched in training and thought was ready last week and it was a wake-up call for Saul and he's not [been] involved this week. The guy's picked up our game very quickly.

"Right now, they're the real deal. First half, Spurs were better. Chelsea landed up winning 3-0. They've got tremendous belief and today was a classic example. That's what separates top teams from good teams."
