Mikel Arteta says winger Bukayo Saka offers Arsenal something "no other player can provide".

The England international won both free-kicks which Declan Rice converted in the Gunners' 3-0 Champions League dismantling of Real Madrid on Tuesday night.

The Hale End academy product, who was playing his third match after returning from a hamstring injury which kept him out since December, was substituted at the Emirates but will be available for Saturday's Premier League clash against Brentford, according to head coach Arteta.

"He's very important, he gives us a level of threat, connection and unpredictability that at the moment no other player can provide us," Arteta told reporters on Friday.

"He has the power to lift the stadium, which is incredible because shifting the energy in the stadium is something which is very hard to do and when a player can do that it's a great addition and quality to have.

"With Declan and Bukayo they are both fit, it was just a matter of them being kicked and they have recovered well."

Following Saturday's Premier League meeting with Brentford, live on Sky Sports, Arsenal travel to Madrid for their Champions League second leg with a great chance of advancing into the semi-finals of the competition for the first time since 2009.
