Everton has always liked to bring in or develop new stars, such as Lukaku and Rooney, whose successful productions (or semi-finished products). However, many of them are "thunderous and rainy" works, and some have not even yet reached their potential.
Buckley
As his own youth, Ross Barkley has received great expectations since his debut; the British media has called him "New Gascoin", which shows how remarkable his talent and talent are. In the seasons at Everton, Barkley showed great talent, his long-range shooting, ball protection, long-pass scheduling ability is very strong, as a midfielder (or attacking midfielder), he delivered 27 goals and 28 assists in 179 games, which is the team's best youth production since Rooney. However, in 2017, he fell out with the team, indicating that he would not renew his contract and moved to Chelsea in the summer of 2018 for a low price of 12 million pounds. But his career with the Blues has been high and low, and he was even more hidden by record problems on the way to Villa last season; this season he has become a marginal man at Chelsea, playing only 428 minutes for the Blues. I believe that Barkley, who is still 28 years old, is still promising, but it is unlikely to play for big teams and giants.
Jack Rodwell
Jack Rodwell was England's midfielder hopeful, having played with England under the U21 for many years, leading the team to the final at Euro 21 in 2009; Jack Rodwell was already in the spotlight before he could gain a foothold in the first team. In 2009, he gradually became a midfielder for Everton, and in 2012, at the age of 22, he played more than 100 games for the team's first team, which showed his precociousness. In the summer of '12, he was recruited by Manchester City for a transfer fee of £15 million, but in the star-studded City, the injured Jack Rodwell did not get too many opportunities, playing only 25 games for Manchester City in two seasons, even if the team won the league title in the 13-14 season, he only played five games. After leaving the Blue Moons, Jack Rodwell played for Sunderland, Blackburn Rovers and Sheffield United, but his performances were no longer what they used to be, and he did not have a "job" for a time. He is currently working for the Australian Professional Games and is playing for the Western Sydney Wanderers.
Brendan Galloway
I don't know if fans are still impressed by the name Brendan Galloway, who was a genius who won the League One at the age of 15 before moving to Everton. In 2014, at the age of 18, he was invited to join Everton and rose to prominence. In the 2015-16 season, due to the heavy damage of Leighton Baines, he was given a lot of opportunities to play, and played 19 games for Everton throughout the season, and performed well on both offensive and defensive ends. He was then loaned to West Bromwich Albion, but it got worse and worse; he only had three appearances in the season. Since then, Brendan Galloway has faded from the sight of fans, floating in the Championship and League One; he is now playing for Plymouth Argyle F.C.) in League One.
Sandro Ramirez
Barcelona's youth production is almost a must-have, and Everton also introduced Sandro Ramírez for £5.2 million in the summer of 2017 to replace the departing Lukaku, which was considered one of the "no-lose" acquisitions at the time. He excelled in La Liga before moving to Everton and scored 16 goals in 31 games for Maratha, while also leading the Spanish U21 team to the final of the U21 European Cup, although the team ended in defeat, he still scored a goal for the team. However, his career at Everton can only be described as miserable, and in the Premier League he only got eight chances to wear the armor and did not score a single goal. He was loaned back to La Liga, but did not fare much during his time for Sevilla, Real Sociedad, Valladolid and even Huesca.
