The Arsenal Supporters' Trust (AST) has urged the club's board to clarify Arsene Wenger's future well before his current contract expires in 2019.

Calls for the long-serving Frenchman to step down from his role at the Emirates Stadium have steadily grown in recent seasons, reaching unprecedented levels last term with regular protests against his continued employment.

Even so, Wenger signed a new two-year deal after steering the Gunners to FA Cup glory at the end of the 2016-17 campaign and is now contracted to the club until at least 2019.

Wenger admitted last season that uncertainty over his future affected the club's form as they lost seven times in a 12-match spell to fall out of contention both domestically and in Europe.

A survey of the AST has revealed that 92% believe that the board did not handle the situation as well as it could have been dealt with, while 90% are unhappy with Stan Kroenke's running of the club.

The survey also revealed that 90% believe that "the board should make a firm decision" and announce Wenger's future ahead of time in order to avoid a similar situation to last term. Two-thirds of those surveyed also wanted a director of football in place, which Wenger has previously opposed.

Arsenal currently sit fifth in the Premier League table following Sunday's 5-2 win over Everton, only outside the top four on goal difference.
