Manchester United striker Romelu Lukaku has copped a lot of criticism again after another a below par performance against Derby County in the Carabao Cup on Wednesday evening. United were stunned by Frank Lampard's side, losing 8-7 on penalties after the match finished in a 2-2 draw.

The club's fans have since blamed Lukaku for not trying hard enough to make a impact after the Belgian also had a quiet game last weekend against Wolves.

The striker had a couple of good chances in the first half against Derby but failed to find the back of the net, with his accuracy letting him down. The 25-year-old came closest in the second half when a powerful shot cannoned off the post.

Lukaku's recent form has forced United fans calling for him to be dropped from the first team. José Mourinho's side travel to West Ham United on Saturday in the Premier League, which will see Marcus Rashford return from suspension. The 20-year-old could be used as an alternative centre forward should Lukaku be demoted to the bench.

Here are some of the Twitter reactions by United fans...
