Steven Gerrard gave Liverpool a lead in the second minute from the penalty spot after Luis Suárez had been fouled in the area.
But the Reds’ advantage lasted a matter of minutes as Jonathan Walters fired past Pepe Reina, before Kenwyne Jones put the Potters ahead.
Stoke wrapped up three points courtesy of Walters’ instinctive finish soon after half-time to condemn the Reds to their sixth Premier League loss of the season.
“We need more experience and need to show more character in these type of games,” Enrique said.
“You can see we have quality players and we have a good squad, but we need to fight for every point we play for if we want to be in the top four.
“We have to get a winning mentality going and we have to show what we are all about. Every game in this league is difficult but you have to give 100 per cent every time you play for this club and show character.”
