Marko Arnautovic started, scored and then was substituted off within the first 20 minutes of yesterday’s FA Cup win.

It was a brief but impressive performance from West Ham’s talisman, who was visibly annoyed by Manuel Pellegrini’s decision to bring him off.

West Ham fans were shocked to see Arnautovic named in the starting line-up, having just returned from injury.

Hammers supporters assumed that Pellegrini would rest the Austrian, who had scored twice against Brighton a few days prior.

Here are what West Ham fans were saying when they saw Arnautovic’s name on the team sheet.

Arnie produced the opening goal just two minutes into the game to set the ball rolling.

Grady Diangana’s excellent corner was headed goal-wards by Angelo Ogbonna. Lee Camp parried the ball away but Arnautovic reacted quickest to nod in from close range.

However, on 19 minutes, Pellegrini decided to substitute the Hammers striker. Arnautovic was furious as he argued with Pellegrini before storming off.

West Ham fans panicked at this point, presuming he was injured, and here are some tweets at the time.

After the full-time whistle, Pellegrini explained this decision in his post-match press conference.

Thankfully for West Ham fans, the Chilean said it was a precautionary measure because Arnautovic had felt a knock.

Pellegrini explained (via whufc.com): “Marko felt a pain in his back and at the beginning he wanted to recover, but he could not continue.

“It was not good to take a risk as he has just returned after an injury and he played 90 minutes less than 72 hours ago and 65 minutes in the other game, so it was good for him not to continue.

“There is no problem and he scored a goal!”

Here are what West Ham fans said later upon reflection of the real reasons behind the decision.
