Manchester United midfielder Ander Herrera has put the pressure on cross-town rivals Manchester City in the title race.

Both Manchester clubs are favourites to lift the league title season, and at present, they find themselves level on points at the summit of the league table.

However, the Spaniard star feels that City are obliged to win the title this season following their heavy spending in the summer.

"City have spent the biggest amount in the Premier League so they are the principle contenders for the title," he said. "We have quality as well but because of the money they have spent they are the favourites.

"We won three trophies last season and City didn't win anything. They are under pressure. They need titles to keep everyone happy. They are obligated to win something. They have more obligation than us.

"We will try to be there. There is pressure when you spend a lot but there is also pressure on us because we are the biggest club in England."
