Barcelona announced on Tuesday an agreement for the extension of youngster's Sergi Samper contract. The midfielder inks a new deal until 2019, gets a €50 million release clause, and more importantly a promotion to the first team. There are no plans to loan him out or keep him at Barça B. Samper is a first teamer now. Period.
If you consider Samper a "first team signing", there are now four new players on the first team. All of them, ALL OF THEM, are 22 years old or younger. Samuel Umtiti (22), Lucas Digne (22), Denis Suárez (22) and Samper (21) are among the best new prospects in their respective positions, and they're all part of Barça's first team.
