Arsenal fans react on Twitter to Per Mertesacker's performance v Southampton

The German struggled up against Shane Long.

Just when you think Arsenal are all set to actually fight for and win the Premier League title again they go and put in a performance like the one they did yesterday.

After their win against Manchester City there is no doubt that Arsenal would not have expected what happened in the fixture with Southampton.

The Saints ran rampant at St Mary's, winning 4-0 against the title challengers.

Cuco Martina scored an absolute screamer to open the scoring but then Arsenal's defence was tormented by Shane Long. He bagged two goals with his raw and sometimes sketchy performance whilst Jose Fonte headed in from close range.

Arsenal had their complaints after the game regarding offsides, fouls and what-not for the goals, however they did not help themselves - especially Per Mertesacker.

The German defender has never been quick but he has developed a way of dealing with pacy forwards. Yesterday however was not one of those performances.

Long had him, and in fairness Laurent Koscielny, on toast for much of the game with his raw pace, strength and use of the dark arts of football doing the trick.

Here is how the Arsenal fans reacted to the performance...
