West Ham fans went wild when Rice gave away the penalty

And he has made a positive start to life at the Emirates, establishing himself as one of Mikel Arteta’s most crucial players.

But it was an evening to forget for both Arsenal and the England midfielder on Thursday.

Goals from Tomas Soucek and Konstantinos Mavropanos saw West Ham claim a famous victory in North London.

And it could have been 3-0 in stoppage time after a nightmare moment for Rice.

The Arsenal star’s poor touch led him to overstretch and bring down Emerson Palmieri.

Referee Michael Oliver pointed straight to the spot as the travelling West Ham fans went wild.

Rice gave a hurt smile after realizing his error, so it was a terrible moment for him.

To keep the score at 2-0, David Raya, however, somewhat saved Declan Rice blushes by saving Said Benrahma’s penalty.
