West Ham's financial situation forced them to cash in on key players like Collins last September. Had Gold and Sullivan not taken over in January then England trio Robert Green, Carlton Cole and Matthew Upson may also have been sold.
"Considering the problems we had since I came over everybody has dealt with the situation well," said Zola. "If you think about it, we were one of the richest teams and became one of the poorest.

"We have managed the situation very well and I'm sorry Portsmouth couldn't do the same.
"Considering the circumstances last year we have done a good job. I don't want to say it was me because the job has been done by a group of people and I shared the good things that we did last year with all of my staff.
"This year we haven't been able to do the same but, if we do well in the last three games, considering everything we have been through it is a decent job."
