Rooney’s double in the Manchester derby took his total to four in United’s last two Premier League games. Before that, however, Sir Alex Ferguson admitted that the England striker was not scoring enough compared to his teammate Robin van Persie.
"Wayne is the kind of player who can score goals, but if someone is scoring more he’s not too bothered," said Giggs.
"He’s quite happy setting goals up and pitching in with important goals like he did on Sunday.
"It’s like when Cristiano was here, he scored a lot of goals. It’s similar with Wayne, he’s not just an out and out goalscorer. He’s more than that. He’s the catalyst to everything good that we do.
"He can score goals, make goals. It’s a massive plus for him to get the goals at City."
