Leicester City striker Leonardo Ulloa admits the Foxes must learn to handle the pressure of being Premier League champions.
Claudio Ranieri's side are 10 points behind leaders Manchester City and have lost three games this season, the same amount they suffered in the whole of last term.
Sunday's 0-0 draw with Southampton extended their unbeaten home league run to 19 games but Ulloa conceded the Foxes are finding it hard after romping to the title by 10 points in May.
"It's so difficult, in every game every team wants to beat us because we are the champions," he told Leicester's official website. "We need to consider that and it's more difficult than the last year. We need to keep going and work. We are improving in training and in every game.
"It was a difficult game, they played well and had some chances so the point was good for us.
"Some players are going with their national teams now and the others rest but we need to think about the next game."
Leicester struggled to break down the Saints and Charlie Austin missed the visitors' best chances when he hit the post in the first half and was denied by Kasper Schmeichel after the break.
