The fruits of the policy this season can be seen this season, with two players signed in the summer of 2024.
Malick Yalcouye, a £6m signing from Gothenburg, spent the past two years out on loan, first with Sturm Graz in Austria and then with Swansea City in the Championship.
The 20-year-old has two Premier League goals in his first five appearances.
Ibrahim Osman, a £17m capture from Danish side Nordsjaelland, was with Feyenoord in the Netherlands, Auxerre in France and Championship side Birmingham City.
The 21-year-old winger has made three substitute appearances so far.
“Malik’s had a really good start to the season,” Cave said. “Osman is another young player who has had three loans now and then has come back into the squad for this season.
“They’re good examples and role models of a commitment to their own development, having an attitude and a desire to want to get better.
“Now we’re starting to see them delivering in the Premier League for us which is a fantastic success story but real testament to them and their hard work.”
One to watch this season is Matias Orozco, an 18-year-old who cost £3.75m from Deportivo Calli. He is with Castellon, who sit second in the Spanish second division.
The defensive midfielder was handed his first senior caps for Colombia during the current international break.
“We do a lot of work in analysing the right clubs, coaches, leagues, understanding how complex it is, to find the right destination,” Cave added.
“Depending on where that player is in their career, what areas of their game we’re looking to help develop, or as just part of their maturity and experience.”
