#1 Lucas Perez
Arsenal forward Lucas Perez was on the verge of joining Barcelona in the summer but chose Arsene Wenger's side instead for the chance of more regular football. Sadly, it hasn't gone according to plan but he remains a player the national team ought to call up soon.
Perez is 28 and is extremely experienced having played in Spain, Ukraine, Greece, Spain again and now in England. He's quick, really quick, has an eye for goal and the technique to ensure he hits the target whenever he honestly tries.
With eight goals and six assists in only his first season at the club, he has the credibility and the experience to make it to the Spanish national team this year. The FIFA World Cup might come a bit too soon, but should he really push on from here and show the selection committee what he is capable of with his performances for Arsenal next season, it might just happen.
