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.
With a handful of reporters awaiting the expected unveiling of goalkeeper Richard Wright from Everton, they got a little more than they bargained for as Campbell was revealed as an Arsenal player.
"We had an agreement that never came out," Wenger told the club's official website. "I remember his press conference, when I said we will announce a player.
"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.
"I realised [how significant it was] when we played our first game at Tottenham," he added. "It was difficult for him but this man is not afraid of big decisions."
