The Leicester City manager was disappointed with the performance which saw his side exit the FA Cup.
Pearson’s team had put in a positive first half display against Villa, but the second half escaped them as the home side emerged energised thanks to a half-time team talk courtesy of new manager Tim Sherwood.
“It’s disappointing and in the second half we didn’t play with the same sort of quality that we did in the first half,” said Pearson.
“That’s really disappointing as it’s more or less the same side that we played against Arsenal and yet it probably sums up why we’re having such a frustrating season in as much as we don’t replicate those performances.”
Pearson now takes his side to Goodison Park to take on Everton next Sunday, hoping his side can rediscover the kind of form which has seen them test several of the top teams this year, with Manchester United the biggest casualty.
One positive from the game was the return of defender Matthew Upson, who was impressive in his second appearance in a City shirt, while Kramaric’s fine headed goal, his second in as many games, will give the Foxes hope ahead of the trip to Merseyside.
“Matt Upson, I’m delighted he got through,” added Pearson.
“I’m pleased for him and the most important thing now for us is to make sure that we get ready for the next game. Again, the fans get behind the team so well and we’ve not given them the performance that they were looking for, and that’s a big disappointment for sure.”
