Man City transfer news: Sell-on clause revealed as Newcastle United sign £3.5m midfielder

Manchester City youngster Alfie Harrison has joined Newcastle United in a deal that could be worth up to £3.5m.

On deadline day, Newcastle confirmed the signing of 18-year-old midfielder Harrison on a two-and-a-half-year deal, subject to ratification.

The undisclosed fee is understood to be a nominal one but some significant add-ons have been included as part of the deal as well as a 40% sell-on percentage, ManchesterWorld understands. The deal could be worth as much as £3.5m should he meet certain performance-related criteria.

Harrison is set to join up with The Magpies' academy set-up. Harrison told the club website: "The size of the club and what it has got going for it is massive for me. It's got a huge, passionate fanbase and I'm looking to really push on with my career now.

"I'm an effective player who can add goals and assists. I really like to create stuff but, on the other side, I'd also say I'm a very passionate player who always wants to win."

Meanwhile, Newcastle academy director Steve Harper added: "We are delighted to secure Alfie's signature. His hunger to represent Newcastle United and continue his development here was obvious from the outset.

"He's a passionate, talented player who we are really looking forward to welcoming to the club and ultimately seeing in a black and white shirt.

"Alfie's signing is part of a strategic move to make our PDP group younger, particularly the Under-21s, and I would like to thank the board and everybody involved at the club in making this move happen."
