i wasn't impressed with his technique much, he seems a bit of a lumbering guy that can score but he needs space and relies on his physicality a lot. in the premier league both those things are hard to find, you are marked a lot tighter and central defenders are all pretty strong so you cannot really outmuscle them as easily as from the videos i saw of him from the portuguese league

but he'll probably still get his share of goals just by being in the right position and having good finishing, and he can learn to adapt to the pace of the premier league over time
