Brendan has yet to fill out a bio.
I haven't watched much of him, but from what I've seen, and read, he was likely acquired to simply provide depth on the wings. He will, however, have a lot of competition considering Benfica already has Ola John, Salvio, Djuricic, Markovic, and Gaitan (if he stays).
Overall, I think he was a decent signing, but I'm not expecting him to step right into the starting 11. He'll likely be a back-up.
Thanks for the info, Brendan. I'll keep an eye out
