Southampton manager Russell Martin says their shock defeat in the EFL Cup is the "most disappointed" he has been since arriving at the club.
Championship side Saints lost 3-1 to League Two Gillingham in the first round of the competition on Tuesday.
"I'm frustrated and I'm disappointed," former Swansea boss Martin told BBC Radio Solent after the match.
"We had too many players who weren't brave enough or didn't want to play the way that we wanted and we paid for it."
Southampton conceded the first goal after only 11 minutes and were unable to find an equaliser before half-time.
