Silva labels Man City's clash with Villarreal as must-win
"This is a very important game for us - we need to get the three points or we will start to lose touch with the leading teams. It's a tough group but we are good enough to progress to the knock-out stages," he told the club's official website.
"In the Premier League we have got a lot of games under our belt and are playing really well - maybe we need to play more Champions League games before we adapt to the competition.
"Villarreal are a great side that pass the ball around and break very quickly - we will need to be on our guard or they will punish us."
