I know there is an allure about the Champions League, but competitively the Premier League is equal to it. If you look at Man City's UCL opponents last season, only PSG and Dortmund would have likely been in the top six of the Premier League. My point being - competitively Jack is essentially playing at the highest levels of football already. Aston Villa played 4 matches against the UCL finalists and 6 against the quarterfinalists last season.
