The Germany international, who joined Chelsea in a £47.5 million deal, has failed to score in his last eight appearances for Frank Lampard’s side.
Chelsea have suffered a blip this month after losing back-to-back games in the Premier League against Everton and Wolves.
And Werner believes Premier League teams who do not play in a midweek European competition have a major advantage in terms of resting between fixtures.
‘It does matter how much you cost. It’s always a bit of pressure when you come to a new club,’ Werner told Chelsea’s official website.
‘But I think I can handle it very well. It’s not something new.
‘The pressure is a little bit higher than the previous years but I think good footballers are the best under pressure and that’s my plan, I can do very well under pressure.
‘The Premier League is a little bit different to my old league. It’s tougher than I thought.
‘The contact here is harder than in Germany, it’s what I expected but not like this.
‘I think it’s hard when you play every three days… and on Saturday against teams that can rest the whole week.
‘It makes it tough to be the best in every game but the Premier League is very fun to play in.’
