The duo were paired together in attack during the closing weeks of last term and started City's final pre-season friendly in tandem, each striker finding the net in a 3-0 win over West Ham in Helsinki.
It was the inevitable reaction to feeble title challenges that saw Guardiola's City finish 15 points behind the victorious Chelsea side in third place and Mourinho's United drift over the line nine points further adrift.
But then there was in 2008 when we were a League One side, City were newly-crowned the "world's richest club' already with many star players - and we beat them in the League Cup at our humble Withdean Stadium home.
Manchester City are many pundits" favourites for the title this year. "I'm a big fan of his, both of his football and his humility".
Hailed as the Brazilian prodigy most likely to hit the heights reached by his compatriot Neymar, the driven Jesus says: "I'm always training, playing or even playing video games, something connected with football".
Chelsea boss Antonio Conte doesn't want any sympathy
The fact Conte also signed improved terms on his existing deal also laid to rest any simmering disquiet over the Italian's future. It is the best players from all over the world playing for some of the top clubs in the world.
"He's a goalscorer and that's why I worked hard to get him here".
I did take Watford out of my picks because I think Andre Gray is a good signing for them and could make the difference. I don't know, we're going to ask the doctor because, of course, he was injured for a long time.

"I am looking forward to play in the Premier League for one of the best teams in England and I will do my best to help the team achieve their goals". I am very thankful for them, I came from the youth section and had really great years there. Watford will be in the fight as well if Troy Deeney isn't performing and Burnley will be be in the mix as Sean Dyche doesn't seem aware that there's a transfer window. "Players here now are so young and will stay for the future". Still, the north London club has kept its key talent - notably Harry Kane and Dele Alli who scored 47 league goals between them last season. Harry Kane is the best finisher with the types of goals he scores so I'd go for him if I had to bet on the nose but I do fancy Lacazette each-way at 10/1.
