Leonardo Ulloa says Leicester City must learn to cope with the pressure of being Premier League champions.
After Sunday's stalemate with Southampton, Claudio Ranieri's side trail leaders Manchester City by 10 points.
Leicester's fortunes have been vastly different from last season, in which they only lost three league games on their way to the Premier League title.
"It's so difficult, in every game every team wants to beat us because we are the champions," Ulloa told LCFC TV.
"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."
Leicester may consider themselves lucky to have grabbed a point against Southampton, as Charlie Austin hit the post in the first half before being denied by Kasper Schmeichel after the break.
"It was a difficult game, they played well and had some chances so the point was good for us," Ulloa added.
"Some players are going with their national teams now and the others rest but we need to think about the next game."
Leicester play Chelsea at Stamford Bridge in their next Premier League fixture on October 15, live on Sky Sports 1 HD, before they host FC Copenhagen in the Champions League.
