Aston Villa take on Arsenal at Wembley on Saturday in the FA Cup final.
Villa take on Arsenal in the FA Cup final at the weekend and they go into the game as outsiders to lift the trophy.
However, Westwood is certain that his team can upset the odds and he feels that there are three players who will be especially crucial to their success.
"We know how good we are, if we play like we can do we can match anyone," he said.
"We've got internationals throughout the team, Fabs [Fabian Delph] and Clevs [Tom Cleverley] are on form, Christian [Benteke] is a real handful for anyone, I'm sure they'll be having sleepless nights about him."
Delph, Cleverley and Benteke have been arguably Villa's three most pivotal players under Tim Sherwood's stewardship so far and they will be hoping to have a big impact at Wembley.
Delph and Cleverley's dynamism in midfield sets the tone for their side, while in Benteke Villa have one of the most dangerous strikers in England.
The towering Belgian forward has racked up 12 goals in his last 12 games and he will be confident of troubling Arsenal on Saturday.
The Gunners have often been guilty of struggling against destructive centre-forwards and Benteke will be hoping to punish any weaknesses on display at the weekend.
