Foyle, who had won the Skrill Premier manager of the month award for January, saw his side only trailing 1-0 at the break, before they were swept away by a rampant Hatters during the second period.
He said: “If you want the truth, they’re a million miles away from us and the gulf between the top half of the conference now and the bottom half is just getting bigger and bigger.
“It’s 1-0 at half time and we were still in the game. Don’t concede early and what do we do? We get caught with a simple header from a set piece.
“It hurts me. Did I see it coming? Yes I did. There’s been problems in the camp for a long time that people don’t see on the outside.”
