Cassanova is a versatile player who can play in various positions, including centre-half, fullback, and holding midfielder. This ability to adapt to different roles has made him a valuable asset to Tottenham's youth team.

As a key member of Tottenham's U21 team, Cassanova has taken on leadership roles, often wearing the captain's armband for much of last season. His experience and skills have also earned him a spot as a substitute for the first team on eight occasions, including appearances in the Premier League and the UEFA Europa League.

With this new contract, Cassanova is expected to continue growing and developing as a player, potentially contributing more to Tottenham's success in the future.
