Newcastle have confirmed the signing of teenager Mehdi Abeid from French side Lens.
The deal to bring the 18-year-old midfielder to the Barclays Premier League has been in place for some time, but the Magpies have now formalised the move on a five-year contract.
Reserve team manager Peter Beardsley said: "We are delighted to bring Mehdi to the club. He is a bright, young talent and we think he has an exciting future ahead of him."
He added: "After an impressive trial with us earlier in the year, I'm looking forward to working with Mehdi and developing his talent."
