Swindon boss Paolo Di Canio was furious with his side after seeing his side draw 0-0 at Hartlepool.
The Italian's disgust was obvious as he watched summer signing Tommy Miller blast a 71st-minute penalty high over the bar.
Di Canio was still imitating Miller's kick in the dug-out 10 minutes later as his side failed to get their season off to a winning start.
Skipper Alan McCormack admitted: "It's two points dropped, a disappointing game. A bad day all round, a terrible day. If we want to win the league we have to come to Hartlepool and win.
"We got a good telling-off in the dressing room. The manager has high standards and we didn't match them. Sometimes it happens to one player, this time it happened to the whole team.
"So we get back on the training ground, watch the DVD and see our mistakes."
The penalty came after Peter Hartley handballed in the area and Miller, who also missed his last spot-kick for Huddersfield in the League One play-off final, blew the chance to sink his former club.
Pools went closest to scoring in a combative encounter, when new signing Steve Howard headed against the post when he met an Evan Horwood free-kick.
The performance and result delighted Pools' boss Neale Cooper as it came on the back of a 5-0 Capital One Cup humbling at Crewe the previous week.
He said: "It was a good response to last week. They all know how I felt about that and we were really good, in hot conditions."
