1 - "let down by poor officials" - he isn't wrong, 3 key calls, 3 clear calls, you can say the official got it wrong, that isn't against the rules., you can't accuse them of taking a bribe or cheating on purpose.
2 - "if they keep getting the right referees" - ie ones that give them free penalties, tenuous, but the FA may try to make it stick
3 - "they've got a cover now, stick up for each other" - that could be called misconduct against refs. He isn't accusing them of cheating, only of not being honest with managers after the game. I think we can all accept that happens.
4 - "to be let down by a team in black today" - again this is objectively true. They made big mistakes
5 - "they all want the celebrity status" - this might be deemed as undermining the refs. This is one that will need a bit more thought to defend.
6 - "my lads have been let down by a team of officials that weren't good enough on the day" -- again objectively true. He hasn't accused them of cheating, but he has accused them of failing, and they have.
7 - "I'll have to ask him for the number for his dad Keith Cooper, he must have influences somewhere" - it was clearly a joke, the joke be in he gets sympathetic refs, but again might be tough to defend against.
8 - "alan whiley has a job on his hands because they're not good enough" - bringing into question competency, isn't saying they are cheating, he mentioned stoke, which backs up this isn't personal about todays ref, it's about the standard of officiating
There are a few comments that will be tough to avoid, mainly 2, 5, and 7
