Confirming player signings

I’m trying to find three other players from pre-2020 Premier League clubs, including youth or reserves. I've noted a few: Jamal Musiala and Bright Arrey-Mbi from Chelsea youth in 2019, Jérôme Boateng from Man City in 2011, and Pepe Reina from Liverpool in 2014. That gives me exactly four! It sounds plausible if they count any signings from PL clubs. However, the user mentioned "seven players," which adds ambiguity to the list. I think I’m on the right track.Clarifying player arrivals

I'm considering two interpretations of player arrivals for the user. If we focus only on senior first-team arrivals, there were 2 before 2020 (Boateng and Reina), and since then, there’s a count of 6 or 7, depending on including loans like Cancelo. The user mentioned 7 since 2020, which aligns with my count including Cancelo.

Alternatively, if counting all levels, there were 4 pre-2020 (adding Musiala and Arrey-Mbi), matching their number. I think the best approach is to confirm these counts, including loans and academy players, and request clarification on their definitions.
