Olivier Giroud praises generous Arsenal starlet Joel Campbell

The Costa Rican scored the opening goal of the game as he aims to replace Alexis Sanchez in the side.

Arsenal striker Olivier Giroud has praised fellow forward Joel Campbell to the club’s official website following their win over Sunderland.

The Costa Rican scored his first goal at the Emirates in the Gunners' 3-1 win on Saturday afternoon, with his goal helping to break the deadlock on the afternoon.

It was a tireless performance from the forward, who must now step up and try to make a big impact on the side in the absence of star forward Alexis Sanchez.

He did just that in Saturday’s crucial win, and Giroud praised him for his generous displays.

"I’m happy for him because he has the opportunity to show his talent,” he told arsenal.com.

"He’s a top guy who is very generous on the pitch because he never gives up.”

"It's not always been easy for him but I always used to speak with him, encourage him and when he’s playing like that he’s very important for us. Hopefully we’re going to see more of him in that form.”

While Arsenal fans will be delighted with the way Campbell has been able to perform this season, they will know he is unlikely to be able to replace Alexis Sanchez.

The Chilean has been in fine form one again this season, having scored six goals already before his untimely hamstring injury.

Campbell is unlikely to be able to replicate that goalscoring form, but his performance against the Black Cats suggest he will certainly be doing his utmost to prove his worth to manager Arsene Wenger.
