Petr Cech's move from Chelsea to arch rivals Arsenal was confirmed on Monday.
The 33-year old Czech Republic goalkeeper has departed Stamford Bridge after 11 years with the Blues where he won four Premier League titles, as many FA Cups, the Champions League, the Europa League and a trio of League Cups.
Cech's arrival at the Emirates Stadium has the Gunners buzzing as they look to end a title drought of more than a decade.
Here are some of the best reactions from the Twitter world:
A host of Cech's new teammates were quick to welcome the 33 year old to the club:

An issue at #afc in recent years has been the shortage of true leaders on and off the field. Cech brings more authority to the dressing-room
