Wasn't exactly a good idea in many ways though, was it? I love Luis as much as anyone. But appointing someone Captain who can hardly speak a word of English renders officially permitted dialogue with referees a bit difficult! Also how could he cajole or encourage youngsters in early matches of their careers?
Remember that awful FA Cup match against Oldham where Raheem Sterling had been booked and committed a foul about two minutes later? The ref summoned Luis to explain the possible red card consequences, and calm the youngster down, but it was like a Martian communicating with two Venusians!
