Manchester City host Everton tonight looking to make it two wins from two in the Premier League.
Former Manchester United star Rooney is guaranteed a hostile reception from home fans on his return to the city.
United’s record goalscorer left Old Trafford in the summer to rejoin his boyhood club and has made an impressive start to life back on Merseyside.
He scored the winner on his Premier League return to Goodison Park against Stoke.
And Fernandinho believes the former England captain will be the danger man again when Ronald Koeman’s outfit come to town.
“He’s a great player, he showed that during the pre-season and in his first league game as well,” said the Bazil midfielder.
“He is a very good player and we will have to be very careful with him.
“He can score in many different ways. We will have to be close to him and not give him any chance to think or to create any chance on goal.”
The pressure on City and boss Pep Guardiola to win trophies this season is immense following a disappointing first campaign for the Spaniard.
Guardiola suffered the first trophy-less season of his glittering managerial career and more failure is not an option.
But Fernandinho has backed his boss and team-mates to handle the heat and reckons City have a chance of doing the quadruple.
“There’s always pressure here to win something,” he said.
“Since I came four years ago, the pressure is there. You always have to win and this year isn’t going to be different.
“It would be perfect if we can win all the trophies. We will see what happens. The most important thing is to be consistent during the whole season and at the end, try to be fighting for the title”.
