Former Liverpool man Graeme Souness has slammed Chelsea striker Timo Werner, suggesting he would have kept Frank Lampard in his role if he had made an effective impact.
The Germany international has struggled to find consistency since arriving in the Premier League from RB Leipzig last summer but put in a Man of the Match performance in Sunday's win against Sheffield United.
Werner won the penalty for Chelsea 's second goal, the seventh he has won for the Blues this season, and assisted Mason Mount's opener.
However, that has not convinced Souness and he believes that Werner will continue to struggle, suggesting he doesn't have the required physical abilities to shine in English football.
"I think he’ll find our football difficult – he is finding it difficult. I think the aggression and intensity, I think he’s a little bit timid for our football," he told Sky Sports.
"If he’s going to be success in our football that has to come. It’s alright saying, ‘he keeps missing chances, he’s getting there’. I look at him and I’m yet to be convinced.
"Chelsea is a team full of really good players, high technique, they get into the last third and attacking third time and time again, they need more than what he’s giving them. If he had done the business Frank would still be in a job."
A goalless performance against Sheffield United means Werner has gone over 15 hours of football since his last Premier League goal for Chelsea and scored five goals in 18 Premier League appearances under Lampard.
However, he has now registered assists in back-to-back matches for Chelsea, showing signs of improvement since Thomas Tuchel's appointment.
