The Gunners climbed into the top five after the north London side claimed a 2-1 victory over rivals West Ham at Upton Park.
The midfielder Santi Cazorla put Arsenal into a lead in the 41st-minute from the penalty spot before Welbeck put the Gunners 2-0 up in the half-time lead.
Here is a selection of the tweets from the Professionals following Arsenal’s 2-1 win against the Hammers.
Typical Wenger. Typical Arsenal. Needed a win to answer critics. Gets a tricky win away vs West Ham. Not the worst skill to have…. #afc
