The Royals led Arsenal 4-0 after 37 minutes and Hunt could have had a penalty to make it 5-0 before the Gunners produced a remarkable comeback to win 7-5 in the Capital One Cup.
Hunt admitted he can't work out how his side lost but did feel slightly hard done by at not being awarded what he thought was a stonewall penalty.
"Still licking my wounds from last night hard 2 swallow that game!!It's in the past & we can only control the now and get better 4 the future!," he posted on Twitter.
"Just watched the game back how I didn't get a peno in the second half is beyond me!!!!"
