i follow the portuguese league a lot and i can say that both Gelson Martins and Bruno Fernandes are 2 great players, for me 2 of the best players to come trough Sporting's academy in recent years, Gelson is more like a winger, speedy, skillfull, has goals and assists in him, reminds me a lot of Nani and Ronaldo in their 1st years; Bruno Fernandes is a right footed central midfielder, can also play more advanced, makes a lot of runs in to the box, shoots a lot, he can definitely strike the ball from distance too, he has a lot of tactical awareness and football brain, he reminds me a lot of Lampard in terms of playing style, i think both players have all the tools to succeed with the proper manager and club and with the right mentality, the question is can they shine outside of Portugal, we'll see, but as history sugests, many players who come from Sporting's academy can make it to the top. Cheers
