Arsenal icon Martin Keown believes that his former side stand a chance of claiming victory over Chelsea in the final of the FA Cup on Saturday.

Club legend Keown is optimistic about Arsenal's chances on the day and believes that his former side is more than capable of overcoming the odds by claiming an upset victory over the reigning Premier League champions.

He told the Daily Mail: "My head tells me Chelsea will win 2-1... but my heart says Arsene Wenger could still pull something out of the hat.

"Seeing Laurent Koscielny sent off and Gabriel stretchered off was a massive blow. Arsenal are up against a Chelsea side that could bring on Eden Hazard and Diego Costa to win the FA Cup semi-final against Tottenham, the second-best team in the country.

"But Wenger still has a fighting chance — if you believe in him you believe this could be his day to win against all odds."
