Summers continued: "My head is spinning. Why are you drinking out of an Arsenal cup? Why?
"I need to understand the logic, give me the logic and the understanding why you would be drinking out of an Arsenal cup.
"That can't happen. You're the manager of Tottenham Hotspur and you're drinking out of an Arsenal cup before kick-off. Are you joking?
"What do you mean he wouldn't see it? You'd notice it if it had an Everton emblem or a United emblem, you'd notice it if it had a Tottenham one.
"If you brought me that and it had an Arsenal one, I'd say 'take it back, I'm not drinking it'.
"The manager of my football club is walking around pre-kick-off drinking out of an Arsenal cup. We're not at the Emirates, we're at Bournemouth.

"It can't be a legitimate picture, it can't be, I need someone to AI, Grok it, double check it, do whatever, ChatGPT it. That can't be a real image."
Upon discovering the image was real, she added: "Get this man out of my football club. Get him out of my football club, get him out. I need to understand the logic."
Away from his cup mishap, Frank has now seen his side win just one of their last six Premier League matches.
Spurs find themselves 14th in the table following their latest setback and are now seven points adrift of the top four.
Their poor form and league position could increase calls from fans for a change in the dugout.
However, he club had previously planned to give the former Brentford boss time to put his own stamp on the side.
talkSPORT revealed last month that Frank's job was not under threat.
The 52-year-old replaced Ange Postecoglou on a three-year deal through to 2028 during the summer.
