CM: Phil Foden (Manchester City)
Age: 18
One of Manchester City's most prized assets, Foden has been turning heads in English football for the last couple of seasons.
He won the Golden Ball at the FIFA U17 World Cup in 2017, helping England lift the title in India. He made only 5 appearances in the Premier League last season but already has 3 so far in 2018/19.
With some of City's first team stars like David Silva and Fernandinho well into their 30's, Foden will get several opportunities to impress Guardiola in the coming months.
CM: Kai Havertz (Bayer Leverkusen)
Age: 19
Kai Havertz became Bayer Leverkusen's youngest ever debutant in the Bundesliga in 2016, and he's already been a first team regular for two seasons now.
He is a technically gifted playmaker known for his ability with both feet and has evoked comparisons with Mesut Ozil.
In spite of the highly competitive atmosphere in Germany, he already has one cap for the senior side, coming on as an 88th-minute substitute for Timo Werner against Peru earlier this year.
