Nathan Holland's continued progress at West Ham United could one day leave Everton with a sense of what might have been.
The 18-year-old winger quit the Toffees in favour of a move to the London Stadium in January, citing a lack of opportunities on Merseyside.
He is already a regular in West Ham's under-23s, however, whom he helped to the final of the PL2 Division Two play-offs with a 2-1 win against Wolverhampton Wanderers on Monday.
And Hammers coach Terry Westley believes Holland could be one of the club's best ever transfers if he carries on at his current rate.
"Holland was very good first half. I mean, wow, he might be one of the best we have ever made," he said, as quoted by Football London.

"To be able to beat people, run past people, it's going out of the game but he gives that threat. He can run past people, he's just brilliant to watch. He's going to go such a long way."
Everton do not appear to be missing Holland in the short term at least, with their Under-23s crowned PL2 Division One champions at the end of April.
The Toffees' academy has provided first team boss Ronald Koeman with several players in recent season, notably Tom Davies, Matthew Pennington and Ross Barkley.

And Holland could have been another, had he been given a chance to impress.
Will Everton regret losing Holland to West Ham United?
