Dunne believes he is the perfect foil for Kevin De Bruyne and his recent displays suggest the Portuguese playmaker is shifting into top gear at exactly the right time.
He told the City website: “When he plays he brings a different energy to the team.
“He's busy, he's getting around everywhere, he's brilliant on the ball. He can play out wide, he can come in the middle, he's got different attributes.
“Bernardo can just move, come off the line and drift in behind people. For the opposition he's difficult to mark.
“He and Kevin De Bruyne really link up well together."
Dunne added: “He's a really top player and he showed his energy again tonight (against Aston Villa). It's nice for him to get a goal, I know he says it doesn't matter who scores but it'll give him a boost of confidence and he might go on a run now and get a few."
