I doubt he'd every become a main starter at Benfica or even have regular appearances at that club. How will he get ahead of the likes of Gaitan and Salvio? There's also Djuricic and Markovic ahead of him. There are also young, promising players like Cavaleiro and Ola John ahead of him. If we're looking at the striker role, then there's Rodrigo, Cardozo, and Lima ahead of him.
Nah, I don't think Jesus actually wants him at Benfica unless he wants to have Gaitan play through the middle, sell Markovic, John, and Rodrigo, and loan out Cavaleiro. Only then can I see space for Bebe in the Benfica squad.
