Eddie Nketiah's loan spell at Leeds United has been credited with setting him up perfectly for life under Mikel Arteta at Arsenal.
The striker spent the first half of last season on loan at Leeds but failed to leave much of a mark before being recalled in January due to a lack of first-team football.
Whilst the plan was to send Nketiah out on loan again, his performances in training impressed Arteta sufficiently enough to keep him at the Gunners, where he has since started to feature regularly in the Premier League.
Nketiah also became the record goalscorer for England under-21s this international break and, writing in the Times, Tony Cascarino predicted big things of the attacker.
He argued that Nketiah's loan spell under Marcelo Bielsa gave him the experience needed to fit into Arteta's style of play at the Gunners.
Cascarino said: "We should be optimistic that Eddie Nketiah can make his mark with the England senior team after he became the record goalscorer for the under-21s.
"The 21-year-old has impressed Mikel Arteta, the Arsenal manager, enough to be picked ahead of the far more experienced Alexandre Lacazette on many occasions.
"It is remarkable to consider how Nketiah's career has advanced this year. He started by returning from Leeds United, where he had spent a few months on loan without really pulling up any trees.
"Normally you would expect a young player coming back to a 'big six' club after a loan in the Championship either to be on the fringes of the squad or to be sent on loan to another team, but Nketiah has become an important player for Arteta.
"He is a better fit than Lacazette for an Arteta team, which is why the Frenchman has found himself in and out of the line-up.
"Nketiah is ideal because he has an incredible work ethic. It is no coincidence that Mesut Özil and Mattéo Guendouzi have been discarded by the manager, while Pierre-Emerick Aubameyang has had to up his work rate."
He added: "I believe this attribute of Nketiah's arose from his exposure to Marcelo Bielsa's intense methods at Leeds.
"Arsenal under Arsène Wenger and Unai Emery were not the fittest team — they were a bit soft physically. So when Nketiah linked up with one of the most demanding managers in terms of physical conditioning, it was perhaps no surprise when he suffered an injury that kept him out for a month."
Cascarino belies Nketiah needs to develop in front of goal but argued that his fitness is now at a level where he can unsettle defenders on a regular basis.
He said: "Although Leeds did not benefit particularly from Nketiah's loan spell there, it did the player himself the world of good. It helped him reach a level of fitness that is very useful to Arteta, who has shown he believes in the player.
"Nketiah loves to get on the shoulders of defenders and turn them before darting in behind with his blistering pace.
"He is agile with quick feet, much like his hero Ian Wright, the former Arsenal striker, which denies defenders the time to settle. He makes clever runs, taking defenders where they don't want to go."
Cascarino added: "There is still more to come from him, too. If he develops greater confidence in front of goal — as I said about Dominic Calvert-Lewin, the Everton striker, a year ago — then you will have one hell of a player."
