Real Madrid striker Kaka has been cut to 10/1 (from 14/1) to join Arsenal with Sky Bet after reports of a move to the Premier League club materialised on Sunday.
The online betting company saw a steady stream of bets for the Brazilian star to move to the Emirates, with Arsene Wenger under pressure to re-invest some of Cesc Fabregas' transfer fee after a lacklustre start to the campaign.
Following the 2-0 home defeat to Liverpool, Wenger moved to 6/1 to be the next Premier League manager to leave his post, with his reluctance to spend money on players annoying some quarters of the Gunners faithful.
Arsenal have been linked to a number of central defenders with Gary Cahill 13/8 to make the switch to north London, Blackburn skipper Chris Samba 4/9 to join and Scott Dann 1/8 to bolster the Gunners backline.
Elsewhere, Didier Drogba is 5/4 to join Tottenham after Chelsea boss Andre Villas-Boas admitted he is uncertain of the Ivory Coast striker's future.
AVB said last week he is hopeful of securing Drogba on a new one-year deal, but conceded on Saturday that no agreement has been reached.
Turkish Super Lig outfit Galatasaray are 5/1 to sign Drogba, with his former club Marseille (12/1) also in the picture.
