Jack Grealish reacts to Chelsea teenager's 'top' display vs Hull City | OneFootball

Everton midfielder Jack Grealish has sent a congratulatory message to Chelsea youngster Jesse Derry, who made his senior debut for the club in the FA Cup fourth-round win over Hull City on Friday.

Derry joined Chelsea earlier in the summer from Crystal Palace on a four-year deal until 2019.

At 18, the young winger is currently still part of Chelsea's development side, but it is clear that he is one of the most exciting talents there.

He has already had five goals and three assists from 13 appearances in the Premier League 2, and a further five goals in seven games in the UEFA Youth League.

It is not a surprise that Chelsea boss Liam Rosenior decided to include Derry in his squad for the FA Cup tie against Hull City.

Thanks to Pedro Neto's hat-trick, Chelsea virtually put the game to bed already with a 4-0 lead in the 71st minute, allowing Rosenior to deploy Derry and his fellow academy star Shumaira Mheuka in the second half.

Derry stayed on the pitch for 13 minutes and completed 100 per cent of his dribbles (two) and passes (six).

"What a night," Derry wrote on an Instagram post after the match.

"An absolute honour to make my debut for this massive club."

There were several familiar faces among responses to the post, such as Tosin Adarabioyo and, interestingly, Grealish and Rio Ferdinand.

"Congrats bro," wrote the Manchester City loanee.

"Was top when you came on also."

Ferdinand, on the other hand, commented: "Memory of a lifetime."

Chelsea teammate Wesley Fofana also made sure that Derry enjoyed his moment in front of the travelling away fans after the game.
