Something of a late bloomer Arnaiz was practically unheard of in the football world 6 months ago, however his goal scoring and all round form last season for Real Valladolid caught the attention of Spanish heavyweights Real Madrid and Barcelona. Unlike the recent trend (Ceballos, Asensio) it was Barcelona who won the battle for the youngsters signature.
He was put straight into the Barca B team to continue his development but 4 goals in his first 11 games led for calls to bring him into a Barca side without Neymar and with new signing Ousmane Dembele injured. He has yet to start for Barcelona in the league but did start for the senior team in the Copa del Rey, and as you may have guessed, he scored, and played a great game. At this rate an senior league appearance is only a matter of time, and a future Spain call up is sure to happen.
