Arsenal fans react on Twitter to Laurent Koscielny's display against West Ham

Laurent Koscielny

Arsenal fans were ecstatic with the return of Laurent Koscielny after his performance against West Ham.

Arsenal had to show their resiliency against QPR on Boxing Day, and they proved it once again with a win against West Ham United.

After a strong start from the hosts, Arsenal took the lead with Santi Cazorla converting from the penalty spot after being tripped up by Winston Reid.

Just three minutes later, Danny Welbeck converted from close range to give Arsenal a 2-0 lead at half-time, which may have been slightly flattering.

Cheikhou Kouyate gave West Ham hope with a second half header, but Arsenal stood strong defensively - and a large reason for that was the return of Laurent Koscielny.

The French centre back has been out for the majority of the season, but made his return this afternoon - and was superb in the Arsenal back four.

Fans were delighted to see the former Lorient star make his comeback, taking to Twitter to praise the man they know as 'Bosscielny'.
