Mikel Arteta has defended Diego Simeone from criticism after Arsenal and Atletico Madrid played out a controversial draw in the first leg of their Champions League semi-final.
The tie is finely poised at 1-1 after each team scored from the penalty spot - Viktor Gyokeres in the first half, Julian Alvarez after the break - but the game ended in controversy after a second Gunners spot-kick was overturned by VAR.
