The club signed Uruguayan winger Carlos de Pena from Nacional shortly before the closing of the transfer window.





The 23-year-old will join Boro on a three-year contract.





De Pena completed the formalities of the deal while in Brazil, having undergone a medical on Tuesday morning, and the player will head to Middlesbrough later this week to join up with the club.





De Pena made 53 appearances for Montevideo-based Nacional and scored 10 goals.





The player becomes our second Uruguayan signing of the summer, joining striker Cristhian Stuani.
