#4 Play Nelson Semedo at right-back over Sergi Roberto
After the horrendous last season under Luis Enrique, one thing that became clearly evident was that Sergi Roberto is not capable enough to play as a right-back.
The 25-year-old Spaniard has frequently demonstrated his excellence in midfield, be it in the 4-0 thumping of Real Madrid in 2015, or in the historic comeback against PSG last season, Sergi Roberto has stood out as a midfielder. However, with his recurring clangers and weak defence, he was bootless as a right-back last season.
The arrival of Nelson Semedo probably meant Roberto will finally switch to midfield for good, but it seems like Valverde has other plans, as he has constantly rotated the Portuguese and the Spaniard at the right-back position, despite the presence of a full-time natural right-back in Semedo.
Aleix Vidal has also been very disappointing at his position and Valverde had no other option but to push him forward and utilize the Spaniard on the wings, where he has performed relatively better.
Sergi Roberto is still more of a utility player in Barcelona without any fixed role and the Catalan giants may find it difficult to keep him at the club if he is not recognized as a full-time midfielder in future.
Sergi Roberto is no Xavi Hernandez, you wouldn't expect him to make defence-splitting passes and dictate the play like Xavi did, but the 25-year-old Spaniard will be much more effective if Valverde uses his traits from the midfield, which is where he truly belongs.
Meanwhile, Nelson Semedo, who happens to be a natural right-back, should be made a permanent feature in the right-back role.
