Arsenal hero Martin Keown believes Manchester City goalkeeper Claudio Bravo will be stronger for his debut at Manchester United.
Bravo enjoyed a winning debut, though was lucky to avoid a red card.
Keown wrote in the Daily Mail: "The way Bravo carried on playing his passes after being put under huge pressure by Wayne Rooney will have pleased his manager.
"It may have been a baptism of fire for the debutant, but he will improve as he gets accustomed to the pace of the Premier League and builds relationships with his defenders."
