He then threatened to resign when it was suggested he may be punished for making so many changes, saying team selection was entirely his business.
He insisted his plan for the Southampton game was not out of disrespect for the FA Cup - which the Lancashire club won in 1953 and reached the final of in 1948 and 1951 - but a decision that was being made purely for practical reasons.
"It's a fantastic competition. I'm not going to belittle it. We'd love to win it but we have no chance with the squad we've got," he said.

"I have somewhere in my mind that I will make changes, but I don't know who will play," he said.
And Newcastle manager Alan Pardew hinted he may make changes from the side that beat West Ham 5-0 for their game against Stevenage.
"It worries me because it's the end of a cycle of games that has been too much," he said.
"[Sunderland boss] Steve Bruce mentioned it - these elite athletes shouldn't be going through this sort of structure.
"This game is our third in a week and our fifth in 13 days, and yet later on in the programme, it opens up a little bit and you have lots of rest."
