Mikel Arteta hails 'exceptional' David Raya but admits Arsenal 'lost control' against Atalanta
Raya ensured Arsenal avoided defeat in their Champions League opener by keeping out a penalty and the rebound from Italy striker Mateo Retegui. Early in the second half, after Thomas Partey was beaten for pace by Ederson and pulled the Brazilian back, referee Clementin Turpin awarded a spot-kick.
