Loaned out in '22. Signed for £34m in '26.

Christos Tzolis arrived at Norwich for £8.8m in 2021 and announced himself with a brace and two assists in a 6-0 cup win. Then it unraveled: relegation, a loan to Twente cut short, a season in Bundesliga 2. Club Brugge rebuilt him — 43 goals and 45 assists in 108 games. Now Arsenal have paid £34m, the biggest sale in Belgian league history, to bring him back to England. Trossard's replacement. No. 17. Five more years.
