Fee: €3.7 million
Contract: Jun 2016
Sporting Lisbon have announced to the Portuguese stock market (CMVM) that they have signed Barcelona winger Jeffren for €3.7 million.
The 23-year-old midfielder has penned a five-year contract with the Portuguese club, with a €30m buy-out clause inserted into the deal.
Sporting have revealed that Barcelona will be entitled to 20 per cent of the profit any future sale of Jeffren generates, with no mention of a buy-back clause for the Catalan club, which had been suggested by the Portuguese media over the last few days.
Jeffren, a product of Barca's youth ranks, has opted for a new challenge after being told he would have little room to operate at the Camp Nou in the new season.
At his official presentation, Jeffren said: "Sporting are a great club. I am proud to be able to represent this club. I am very happy with the trust they have in me. My goal is to grow in this team. I can grow and evolve, to become a better player."
The Spain Under-21 international has become Sporting's 14th signing this summer, and the second Spaniard to arrive at the Estadio do Alvalade in the transfer window, following the acquisition of Sevilla's Diego Capel for €3.5m last month.
It is believed that Jeffren will immediately join up with the rest of the team as they will participate in the Ramon de Carranza trophy at the weekend, together with Cadiz, Malaga and Udinese.
