Former Red Devils man can see similarities between the two fierce rivals and expects Roberto Mancini's side to get a hunger for winning trophies if they win the FA Cup
Kidd served as understudy to Sir Alex Ferguson during the mid-90's when United began collecting trophies with gusto and now believes City are gathering the spirit needed to become a trophy-winning side.
"Manchester United won the FA Cup in 1990, then the Cup Winners' Cup the following season," said Kidd, according to Sky Sports.
"They lost the league to Leeds the following year, which proved to be the prelude to what they are now.
"Recovering from that setback showed how much spirit there was at Old Trafford. I feel there is a lot of that with City."
Manchester-born Kidd won the European Cup with Manchester United and helped guide them to success prior to taking a seat in the dugout at City and whilst thrilled with the club's 1-0 triumph in Saturday’s FA Cup semi-final, the 61-year-old was also thrilled for his city of birth.
"It is great for Manchester football," added Kidd.
"I was looking round just before kick-off. I saw one half of the stadium red, the other blue. For me personally, it was a wonderful moment.
"You can have wonderful nights playing against the best teams in Europe. That is what we are striving for."
Kidd will now have to help Roberto Mancini ensure City’s players don’t get carried away with the euphoria generated by Yaya Toure’s second-half strike which sunk rivals United at Wembley as they bid to deliver a top-four league berth and a first trophy for 35 years.
"We can only enjoy this win for a couple of hours, then we must prove our mettle," added the former Blackburn Rovers boss.
"After 35 years, now we have a chance to win a trophy.
"It is all a learning process for our players but when you do win something, it is intoxicating. You should just become hungrier for even more."
