Yups... An advantage for Manchester City because Pep Guardiola can rest the main players and try to play some of the second line players in the 2nd leg.
Before playing the Manchester derby match, Manchester City will face Luton Town in the FA Cup tournament. Again, in my opinion, Pep Guardiola can rest several main players to ensure several main players are fit against Manchester United.
Luton's quality is not comparable to Manchester City's, but if Pep Guardiola is serious about the FA Cup, not all players will be completely rested. Pep will bring them on with just a few moments remaining before the end of the match.
Because it concerns the minute a goal is scored, just think about all the potential these two Manchester teams have. Good luck.
