He has much more potential to showcase his strengths, but its only the first week, and thats normal. Im seeing him improve a lot, and with his speed and finishing ability, hes doing well. He has a lot of potential and can contribute a great deal.Its hard to see Adeyemi becoming a fixture of the starting XI, but hes got the right combination of skills and versatility to make him a very useful super-sub type forward who can play all three positions in attack and do a job whenever hes called into action.If Adeyemi can become what Pedro was for Baras Treble-winning side of 2015, his signing will be worth it already.
