Didn't see him much while at Porto, so have no idea what to expect from the 'real Pereira', if such a player exists, but so far in black and blue he comes across as a sometimes tactically unaware, rusty and irritating (diving, acting) left back, who does not give too many options going forward. Considering his reported price tag, he is an even bigger flop so far, than Rocchi, who at least wasn't even expected to do well...
