Borussia Dortmund 2-0 Arsenal: player ratings for Champions League loss, as Hector Bellerin has tough debut

LB) Kieran Gibbs – 5

Was rushed back from injury to play, and struggled against Dortmund’s pace in attack.

CB) Per Mertesacker – 6

Also struggled with Dortmund’s pace, but was arguably the pick of Arsenal’s shaky back-line. Won plenty of headers.

CB) Laurent Koscielny – 5

Not strong enough against the players he was meant to be marking. Immobile went past him as if he wasn’t there.
