Mata feels they go into the game in great shape.
He told Absolute Radio: "Always playing against Liverpool is a tough game, and I realised last season when we lose in the Carling Cup, in league as well, playing in Anfield, and I think we have to be strong at home. We are feeling really good playing in Stamford Bridge with our supporters, with their support, and it's going to be tough, but I think if we want to win this Premier League we have to be at the level in these kind of games, which are massive rivals."
Mata was speaking to Ian Wright of Absolute Radio Rock n' Roll Football. Saturday's from 5pm on 1215AM. For more, visit absoluteradio.co.uk/football
