Slaven Bilic believes West Ham can start turning around their Premier League form after the confidence boost of a Carabao Cup victory.
Diafra Sakho and Andre Ayew struck just before half-time as West Ham ran out comfortable 2-0 winners at Cheltenham to reach round three.
Hammers boss Bilic had the look of a relieved man after avoiding a cup upset on the back of conceding seven goals in opening Premier League defeats to Manchester United and Southampton.
"Nothing gives you confidence like a win so this is very important," Bilic said.
