Ghana winger Christian Atsu has credited Leicester City goalkeeper Kasper Schemichel for a rousing speech which led to the Foxes 2-2 draw with Stoke City.
Leicester came from 2-0 down at the Bet365 stadium on Saturday to grab a 2-2 draw against the Potters with 10 men after Jamie Vardy had been sent off after 28 minutes.
Vardy was shown a straight red card by referee Craig Pawson for a two-footed tackle, sparking a furious confrontation from manager Claudio Ranieri on the pitch at half-time.
Schmeichel could be seen leading his manager away from the referee and Amartey has now revealed that the Danish goalkeeper addressed his team-mates again in the dressing room before goals from Leonardo Ulloa and Amartey clinched an unlikely point.
"When we went inside [Ranieri] talked to us, Kasper talked to us and we talked to each other," Amartey told the official Leicester City TV channel.
"We had to come back and fight together.
"When you're on the bench, you have to be ready every game because you don't know what could happen. I'm very happy for Demarai and those that came in to change the game and help us."
Leicester next face Everton at the King Power Stadium on Boxing Day but face doing so without Vardy, should any possible appeal fail, as well as left-back Christian Fuchs and centre-half Robert Huth who picked up their fifth cautions of the season at Stoke.
