A delighted Joseph Guardiola praised his team's first-half performance and jumped to the defence of Manchester City's new goalkeeper Claudio Bravo.

"In the second half, he continued to play and that's a good thing about his personality. He was one of the reasons we played well in the first half," Guardiola said.
Jose Mourinho, though, was adamant that referee Mark Clattenburg should have awarded penalties when Bravo, having lost control of the ball in his own area, lunged in with studs showing to tackle Wayne Rooney and also when a cross hit Nicolas Otamendi's arm.
"Mark made two big mistakes. Claudio Bravo is a penalty and a red card," Mourinho said.
"The second one is a handball by Nicolas Otamendi - some pundits will say no because it's the back of the arm but he knows. He's looking at the ball. We are not happy with these decisions."
