Arsene Wenger is set to make an announcement on his future tomorrow, with the Arsenal manager understood to have finally agreed a new deal with the club.

Wenger, 57, was out of contract at the end of the season, and there had been added uncertainty following the controversial departure of former vice-chairman David Dein in April and the summer sale of Thierry Henry to Barcelona.

However, the French coach — who brought an unprecedented spell of success to the Gunners since his arrival a decade ago — is understood to have reached an agreement with the board to remain in charge for a further three years.
