The 23-year-old admits Roberto Manciniâ€™s men are in good form but insists United must focus on themselves and ignore the hype about their opposition.
“Manchester City are doing very well, they’ve improved a lot but, in my mind, we only care about us,” he said. “We don’t underestimate any team, we always expect them to be difficult.”
The Mexico international knows United, who have beaten City 67 times in their 159 meetings, will have to produce one of their best performances to upset the league leaders.
“City have a good manager,â€ said the striker. â€œThey’ve spent a lot of money and are doing great but I think, with the history of a club like Manchester United, we know most teams want to win against their rivals.
“We need to be at 100 per cent because both teams want to win this game.
“It’s a very big game for us and the city of Manchester and both sets of fans. Manchester City are at the top and Manchester United always want to be at the top.
“It’ll be a very, very big game and hopefully we can get all three points.”
Meanwhile, City manager Roberto Mancini insists he can learn a lot from his United counterpart Sir Alex Ferguson, hailing the 69-year-oldâ€™s unrelenting thirst for success.
â€œHe is a teacher and I can learn from him,â€ said Mancini. â€œIt is not just me, it is all the managers. He has won everything for 25 years but he wants to continue to win.â€
