It's not every day that a club signs one of their rival's stars, but when it does happen, you should celebrate in style.
Arsenal lured Tottenham centre-back Sol Campbell across the north London divide to the consternation of Spurs fans back in 2001, with the England international joining Arsene Wenger's Gunners on a free transfer after his White Hart Lane contract expired.
Campbell went on win two Premier League titles and three FA Cups with Arsenal, forming part of the 2003-04 'Invincibles' side that went unbeaten in the top flight.
Most modern-day transfers are carefully choreographed affairs between clubs, sponsors and players, but Wenger took great delight in springing a surprise on the press on July 3, 16 years ago.

"Nobody turned up. It was here at the training ground.
"There were only two press people here. I will never forget the press' faces when Sol came in.
'Sol Campbell from Tottenham'... they couldn’t believe it!
"Sol definitely knew before the last week [of his contract] that he was signing for us. At least, before that he promised to sign for us."
Wenger acknowledges that while Campbell took a risk in signing for Arsenal - with Spurs fans turning on him instantly and forever since, also missing out on an invite to the club's White Hart Lane farewell - the defender had the character and confidence to make such a move a success.
