Anthony Barry is the man.
He became assistant manager of Wigan in 2017 at the age of 31 and helped Paul Cook to win League One impressively.
He studied for his Pro licence alongside Frank Lampard in 2020 and qualified with the top marks in the group. He did a dissertation called "The undervalued set-piece" in which he analysed all 16,000+ throw ins taken in the Premier League over a year to conclude the optimal approaches. The dissertation was published. On the back of this, Lampard took him to Chelsea as his assistant.
He was a Chelsea assistant to Lampard, Potter and Tuchel with the latter describing his work on set pieces as "far more advanced than anything I've seen". Tuchel then persuaded Bayern to pay Chelsea compensation to take Barry with him there.
In addition to his club work, Barry has also been involved with international set ups. He was an assistant for Republic of Ireland before working for both Belgium and Portugal under Roberto Martinez.
Barry has turned down head coaching jobs in the past to develop himself as a coach, learning from the best and absorbing different cultures.
A 37 year old, hugely rated coach, with a background steeped in analysis, development, attention to detail and tactics.
We may have to wait until the end of the season to get him, but he's the top target.
This is an in depth article on his rise from Wigan to Chelsea if anyone wants to read more. He's very highly respected.
