Former Arsenal defender Martin Keown has predicted a key battle between David Luiz and Chelsea striker Olivier Giroud in the FA Cup final.

In just a few hours, we will get to see the battle between the two London sides at Wembley.

While there will be a lot of battles on the pitch, Keown picked out one key clash which could have a big impact on the final result.

He wrote in his column for the Daily Mail: “Today will see Olivier Giroud against David Luiz — the former Arsenal striker against the former Chelsea defender.

“Giroud got the better of Victor Lindelof in the semi-final by getting in front of the United man to score from Cesar Azpilicueta’s cross.

“Arsenal cannot allow that to happen today.”

Giroud has been in a hot form since the Premier League restart, scoring seven goals from his last 10 appearances in all competitions.

While Luiz appears to regain his confidence in a back-three system that Arsenal might use in the final.

Keown also pointed out that Chelsea produced more crosses than any other team except for Liverpool and Manchester City in the Premier League this season.

Therefore, aerial battles will be one thing Arsenal defenders have to pay extra attention to.

“Getting his head on the end of a cross was how Giroud opened the scoring against Arsenal in last year’s Europa League final,” he added.

The BT Sport and BBC pundit also expects Frank Lampard to stick with the 3-4-3 system he used in the past two games, including in the semifinal against Manchester United.

He highlighted how Chelsea “pinned Ole Gunnar Solskjaer’s players back” with the system and forced the ball towards wingback Aaron Wan-Bissaka.

“If Arsenal go 3-4-3, too, we are bound to see a good battle between two sets of wing backs,” he wrote.
