Newcastle United owner Mike Ashley has told a High Court judge that a finance expert who says he reneged on a £15 million deal struck during a night of heavy drinking is talking "nonsense".
Investment banker Jeffrey Blue says Sports Direct boss Mr Ashley promised to pay him £15 million if he used his expertise to increase Sports Direct's share price to £8 a share.
He says Mr Ashley paid only £1 million and he wants £14 million damages.
Mr Ashley denies the claim.
He told Mr Justice Leggatt on Wednesday: "It's nonsense."
Mr Justice Leggatt began analysing evidence at a High Court trial in London on Monday.

"It was a fun night, as it was intended to be, and everyone was on good form.
"We got on well, so much so, that we ended up going out after the pub to a bar in the West End where we stayed until the early morning.
"I had drunk so much that I can't remember which bar we went to.
"I don't remember Mr Blue joining us and I can't remember what time he left."
Mr Ashley added: "I find it incredible that Mr Blue is actually suggesting that I made a binding agreement for £15 million.
"If I did say to Mr Blue that I would pay him £15 million if he could increase (Sports Direct's) share price to £8, it would be obvious to everyone, including Mr Blue, that I wasn't being
