Chelsea have been blown away by Levi Colwill's progress at Huddersfield Town.
The 18-year-old is currently on loan with the Terriers, who are fifth on the Championship table.
A ball playing centre-back, Colwill has made 20 appearances in the league so far this season.
And people inside Chelsea's academy are shocked with how easily Colwill has taken to senior football, according to Football London.
Thomas Tuchel will undoubtedly be looking forward to Colwill returning for preseason in the summer.
The Blues are searching for defensive reinforcements with Antonio Rudiger and Andreas Christensen potentially leaving the club.
