West Ham United supporters were given a bit of a scare by the club's official Twitter account on Wednesday.

Indeed, a message of 'good luck, Arnie!' was posted above a story on the attacker.

And immediately a number of the West Ham fans jumped to the conclusion that the 29-year-old would be leaving the club this summer.

In fact, the message was simply there to wish Arnautovic luck after being called up to the Austria squad for a trio of international matches against Russia, Germany and Brazil.

Arnautovic scored 11 times in 35 appearances for the Hammers during the 2017-18 campaign, with all 11 goals coming in 31 Premier League matches.

New head coach Manuel Pellegrini will surely look to build around the popular attacker next season, but the West Ham fans feared that he could be leaving for pastures new when they misinterpreted a post on social media.

No harm done, but it certainly set a few pulses racing. A selection of the Twitter reaction can be seen below:
