Manchester City is no doubt the favourite to win today's UEFA champions league final against inter Milan and I think Pep is going to play the same line up he used against Real Madrid in the semi finals. Pep Gardiola still has a lot of quality players like Mahrez, Foden, Alvarez etc. in the second team that he can always bring in to make a difference.
Pep and Manchester City are very flexible with tactics that is one of biggest challenge for Inter Milan. They won't know how Manchester City will begin and play in the final match. It will be difficult for Inter Milan to choose tactics they start in the final and how to react to tactical changes from Manchester City in the match.
Lautaro Martinez is Inter Milan's top goal scorer and assist maker for the season with 24 goals and 9 assist in all competitions while Lukaku and Dzeko are both in second position with 13 goals to themselves. Lukaku has 7 assist to his name while Dzeko has 4 assist, If Lukaku is fit enough, I think his assist record can give him an edge over Dzeko for a starting place in the final.
Inter Milan will have two main options in the final match. Play defensively with Catenaccio like a traditional Italian club. Play attacking proactively to make Manchester City surprised and get advantage with one or two leading goals like how they broke AC Milan defense in the first semi final. Manchester City are stronger than AC Milan so Inter Milan will need one leading goal to start playing fully defense after that.
If Inter Milan can score first and lead Manchester City in the final, the match will become more exciting as Manchester City will have to play fully attacking to get an equalizer at least. It will be a big test for Inter Milan defense but also will give them chances to show their power in counter attacking.
