"The word resign doesn't come into it," said Worthington. "I have signed a long-term contract at this football club and I intend to honour it.
"Taking flak is part and parcel of the job. You can like it or lump it, but that's a fact. It's not something that you like, but it is there and you have got to deal with it, and fortunately I am quite thick-skinned."
Echoing the sentiments of his directors, Delia Smith and Michael Wynn-Jones, in their statement yesterday, the Ulsterman added:
"The best way I can deal with it is to roll my sleeves up, work as hard as I can, get the players to do exactly the same - and work through it together.
"You are going to have your good times and your lean times. When you go through your lean times you have got to pull together, be even stronger and stick with the principles of what you are trying to do."
