Liverpool's first-team assistant goalkeeping coach Jack Robinson can attest to how the clinical finishing of Curtis Jones, Rhian Brewster and Harvey Elliott can make life for those between the sticks a 'nightmare'.
Robinson had experience of working with the attacking trio at various age groups within the England national team set-up before joining the club in 2018.
On Merseyside, he's seen how their already-impressive potency has gone up another level due to their exposure to Jürgen Klopp's Reds and working closely with Pepijn Lijnders, Peter Krawietz and elite development coach Vitor Matos.
Robinson told Liverpoolfc.com: "You sort of get an idea for how good they are, but then you put them into the environment that they've had with Vitor and the first team, and with the finishing sessions that Pep and Pete put on as well, they are a nightmare.
