There are and always will be better options than players who are not your very best. This doesn't mean they aren't good enough.There were and are better options than JFS and Otto. Otamendi was never a great defender, in 5 seasons with us, he had one outstanding season, that apart he was always likely to mess up at least once a match. At our level that is unacceptable.
Otamendi has started on every team he has ended up at. He is a starter at any level.
