Manchester United have announced the arrival of Uruguayan winger Facundo Pellistri from Penarol on a five-year deal, with the option to extend for a further year.

The 18-year-old becomes United's fifth signing of the transfer window alongside compatriot Edinson Cavani, Alex Telles, Donny Van de Beek and Amad Traore, who will join at a later date.

Speaking to the club's official website, Pellistri said: "To join a club with the history of Manchester United is a dream come true. I have learnt a lot at Penarol and I would like to thank them for everything they have done for me. To have the confidence of the manager is an amazing feeling and I know that working with him will be perfect for my development.

"I am coming into a squad full of great players who I will learn from every day. Everyone knows that Manchester United is a club that gives young players an opportunity and I am ready to work hard every day to earn those chances and prove myself in England."

Red Devils manager Ole Gunnar Solskjaer added: "Our scouts have followed Facundo for a long time and we believe that he will be a real talent for the long term. Whilst we understand it will take time for him to adapt to the English game, he is capable of having an impact with his pace and ability to beat his opponent.

"Facundo has the perfect platform at Manchester United to develop and he has all of the technical qualities and the right mentality required to become a top player here. We are all looking forward to working with him to fulfil his potential over the coming years."

Pellistri made 37 appearances in all competitions for Penarol after making his debut last August, registering two goals for the Primera Division side.
