The former Liverpool defender was writing in his weekly column with The Telegraph and believes Lukaku is the exact same player the Red Devils had during he’s spell in Manchester. There was a thought that Chelsea were getting a different player after he’s successful stint with Inter Milan. But the Sky Sport pundit Carragher thinks differently;

“When Romelu Lukaku signed for Chelsea, the consensus was that he was a different player to that which left Manchester United.

Six months later, there is only one valid observation to make about his return to Stamford Bridge. He isn’t.

All the talk about how a couple of years working with this weekend’s opponent, Antonio Conte, have elevated Lukaku’s game tactically has proven premature. Thomas Tuchel is managing the same striker who prompted Manchester United to run out of patience and sell him to Inter Milan.

That’s why I can’t help but think there is a time bomb in the Chelsea dressing room, with the player and club already losing patience with each other…

Nothing has changed despite his Serie A success. Something is missing to make Lukaku the complete package, worthy of being talked about alongside the world class centre-forwards of this era.

Tuchel clearly wants more from Lukaku, too. You can see it in his touchline demeanour, and hear in his post-match comments…

If his form does not improve it will become a problem the club will have to consider between now and the end of the season, weighing up as to whether they will need another solution up front when planning for a renewed title bid next year.

The recent controversy over ‘that’ interview – in which Lukaku spoke about how much he missed Inter – felt overblown to me…

Had he been flying, with Chelsea still in the kind of form which kept pace with Manchester City until early December, would those comments have been received the same way? I am not so sure.

To me, it was a sign of deeper misgivings across the club as to whether Lukaku will make a return on Chelsea’s investment.

It is too soon to say paying £97.5 million to re-sign Lukaku was a mistake. If there is no radical upturn in form and Tuchel loses trust in the striker ahead of the biggest Premier League and Champions League games, it could become one.”
