It's the first time we've used Spector as a centre-back and he was good.'
Spector added: 'I'm used to being back there. I played in that position throughout my career with youth national teams and club teams.'

Zola has insisted he is keeping Upson, despite interest in the summer and expected offers in the New Year.
And Upson has insisted he is 'fully concentrated' on West Ham ahead of the World Cup finals in the summer. Upson added: 'I don't think I have made many mistakes individually this season but we have conceded a lot of goals.
'That is a problem and something we need to get better at. But I won't let it affect my international aspirations. I am at West Ham, that is my club.'
