Arsenal fans angry at Santos after taking Van Persie's shirt at Half-Time

Arsenal fans reacted furiously on Saturday afternoon after Andre Santos made a beeline for former team-mate Robin Van Persie and asked for his shirt as the players walked off at half-time of the Premier League clash at Old Trafford

I think the fans were angry because it had been the closest anyone got to the Manchester United striker in the first 45 minutes  and fans were angry at the perceived lack of professionalism.

And they let their feelings known via twitter.

On Twitter, @LBFutbol wrote: 'Santos shouldn't be allowed to come back on the pitch after that,'

another added, 'Incredible demonstration after that shambles of a 45 minutes from the "defender".'

Others, including @GoonerTalk, said, 'Unbelievable', @wilforiley added, 'Andre Santos... The single biggest joke to ever wear the Arsenal shirt', and ‏@EddieBaby66 wrote, 'I present to you.... Andre Santos. Truly shocking'.

I guess he must have learnt his lesson.
