For the city faithful theres been a lot to cheer this season. Group winners and through to the last 16 of the champions league, and seemingly unstoppable domestically. Theyve won 13 consecutive games in the premier league, equalling the record. They havent lost since the start of april when they were beaten by chelsea and so far this season theyve dropped just two points, scoring more goals than any other team. How much does that record of consecutive wins play on your mind, if at all . You think about that . No. Absolutely nothing. If you are going to play one game, you forget what you have to do to win the games. It would be nice because it means we won, but sooner or later the record is going to be broken, so.

For those who followed the ups and downs theres a buzz about this current generation. Expectation that city will be the manchester side. Back to young scored right the way through the side there was control of the ball, the passing of the ball, the accuracy of the passing, confidence and belief in each individual player. Ive never seen anything like that before in my career. So for Manchester City the sta kes a re career. So for Manchester City the stakes are higher. Win this weekend and they will set a new premier League Record for consecutive wins ina League Record for consecutive wins in a season and they could set themselves up for a Third Premier League title and usher in a new era of dominance. But united have their own record to preserve. 40 matches unbeaten at old trafford, 41 on sunday would be a new high. In fact the last time they lost here at home was back in september, 2016. And to beat them then . City. For the people born in the city and feeling the colours in that would, positive rivalry, i think its a special match. Whether you are a red or blue 01 even match. Whether you are a red or blue or even not even match. Whether you are a red or blue 01 even not even for match. Whether you are a red or blue or even not even for manchester at all, this derby isntjust a special occasion, it is the biggest game of the premier League Season so far.

They could have lost their manager to rangers, but aberdeen repaid Derek Mcinnes for staying at the club with a 1 0 win at dundee.
