Rotherham boss Paul Warne said he was ready to congratulate Sutton United counterpart Matt Gray before his side staged a dramatic comeback to seal a 4-2 victory after extra time in the Papa Johns Trophy final.
League Two Sutton led 2-1 and looked to have sealed an unlikely win over the League One leaders before Jordi Osei-Tutu equalised in the sixth minute of added time at the end of the second half at Wembley.
Donovan Wilson fired the U's into a first-half lead before Ben Wiles' stunning strike levelled for Rotherham before half-time.
Sutton captain Craig Eastmond's cool finish again gave the south London side the lead early in the second half, only for Osei-Tutu's strike to make it 2-2 right at the end.
Goals in extra time courtesy of Chiedozie Ogbene's long-range effort and Michael Ihiekwe's header sent the Millers fans into a frenzy and ensured the trophy would be heading back up north to South Yorkshire.
"I'd considered with about two minutes to go to shake Matt's hand and say well done," said Warne. "I just didn't think it was going to be our day to get that equalising goal.
"When it went into extra time I just felt a bit more comfortable that we looked a little bit fitter. I'm not being disrespectful to the opposition but I just felt like we looked like we had healthier players on the pitch.
"Fair play to Sutton, I thought they were really good, they were brave with their shape."
