For Saturday's FA Cup final between Arsenal and Chelsea, new and existing Betway customers can earn a £5 free bet every time the team you back to win scores.

This match-up has not guaranteed goals over the past few seasons, but there’s reason to believe that there’ll be plenty of them this time around.

Arsenal’s defensive crisis will have Chelsea’s eyes bulging.

At best, Rob Holding, Nacho Monreal and the recently-concussed Shkodran Mustafi will line up in the Gunners’ back three, with the undercooked Per Mertesacker prepared to step in if needed.

That leaves them vulnerable to Antonio Conte’s attacking riches.

Diego Costa – who has scored three goals in his last five matches – should take advantage, and is a good bet to score first at .

A semi-final brace against Tottenham, meanwhile, means that Willian is worth a punt to score at any time at .

The Premier League champions to net over 2.5 goals, meanwhile, looks a fine bet at considering their form.

The Blues have scored three or more in six of their last seven matches, including the semi-final win against Tottenham and 3-0 victory at Everton.

Backing them to win this match at , then, should guarantee you free bets.

But Arsenal will not go quietly.

Arsene Wenger’s side have scored at least twice in all of their five matches since the north London derby, and have never failed to score at the new Wembley.

Considering, too, that Chelsea cumulatively conceded four goals to woeful Watford and Sunderland sides in their last two matches, they can clearly be breached.

Arsenal can be backed to score over 1.5 goals at .

Alexis Sanchez is the obvious bet to notch first for the Gunners in this one, at , after scoring in the semi-final.

The Chilean has managed five goals in his last four outings, too.

Olivier Giroud will likely start ahead of Danny Welbeck, though, and is worth backing to extend his run of three goals in three matches at .

The north Londoners are certainly worth a punt to win this one at , with free bets a likely reward at least.

Considering that four of the last five finals featuring Chelsea or Arsenal have contained over 2.5 goals, meanwhile, a bet on a repeat is decent value at .
