It is easy to ignore the contribution of Isa because he is a no frills professional. He is not going to make many 50m breaks but what he does has earned him everyone's respect. Compare that to our initial doubt when he signed. Perhaps , sometimes, the club does know a bit more than we do. Personally, I find that my life is made immeasurably easier when my colleagues do what they are meant to do well, no matter what their rank of pay cheque.
