Manchester City playmaker David Silva feels that Pep Guardiola's side are hitting top form at the perfect time of the season.

City are currently on a four-game winning run in the Premier League and have also registered positive results in the Champions League and FA Cup.

"We have to believe," said the Spanish midfielder following the 2-0 win over Sunderland.

"We know the last two or three months are the most important part of season.

"We're in a good moment.

"We need that. To keep the intensity high. He's always behind us and pushing us. It's good for the team and you have to do that."
