RB: Sergi Roberto(Spain | FC Barcelona)
Spain's unbelievable squad depth means a few of the talented players obviously missing out on World Cup 2018. One of those players is Sergi Roberto who has made the Right-back spot his own at Barcelona for the last two seasons. Hailed as one of the most versatile players of the current generation, Roberto has not been able to cement a place in the Spanish National Team.
A star-studded midfield and an ever-reliable Dani Carvajal prove as hurdles for the young Barcelona man, who must consider himself unfortunate.
It is sad that a player of Sergi Roberto's calibre missing out on Russia 2018 but such is the quality of Spain that they can leave out players like Roberto, Fabregas, Gabi and yet put up a full-strength squad. A headache, Lopetegui will be glad to have.
