Barnet boss Lawrie Sanchez believes his side were beaten by a Championship team after their Wembley dreams were dashed by Swindon.
The Bees travelled to the County Ground all square at 1-1 in the Johnstone's Paint Trophy Southern Area final.
But Swindon grabbed the winner after 17 minutes - with Barnet's Mark Hughes off the field receiving treatment - as Alan Connell found space to meet a perfectly weighted delivery from Paul Caddis.
"We were playing the best team in the league - whoever will finish above them will win the league," said Sanchez, who saw striker Charlie Taylor sent off late on.
"I give credit to Swindon. I think they are a Championship side in League Two. I think they will probably win the league.
"They have a massive squad and a bigger wage bill than us. It took an awful long time to get Mark Hughes back onto the field. If we got him on quicker, then who knows?"
