Chelsea winger Pedro has admitted he is having to come to terms with the "physicality and competition" of the Premier League, having joined the Blues from Barcelona for £21 million in August.
The Spain international scored on his debut for Chelsea in a narrow 3-2 victory away to West Bromwich Albion, but has not scored in the league since.
Pedro's slow start has matched Chelsea's form in the early part of the season, which sees them ten points short of league-leaders Manchester City and far from the form that will see them retain their title.

Speaking to the Mirror, Pedro said: "It’s hard. It’s very different to what I’m used to [at Barcelona].
"But, little by little, I'm integrating more, adapting with my team-mates and the team and that's the most important thing."
Fellow Spaniard Cesc Fabregas has also struggled this season, failing to recreate the form that helped the Blues to the title last campaign, having also joined the club from Barcelona.
"Everything is different, very different to the football I'm used to. I think there are a lot of differences, very physical football, very strong," Pedro continued.
"A lot of players attack and it's always complicated. All the games are competitive and very balanced."
Luckily for Pedro, he has kept his place in the Blues' starting line-up thanks to his willingness to help out defensively, unlike Premier League Player of the Year Eden Hazard, who has been dropped by manager Jose Mourinho.
"I will continue that way, or he comes in our direction and tries to emulate the same work that Willian and Pedro put in," Mourinho admitted.
Pedro has made nine appearances for Chelsea this season, with his only other goal coming in the League Cup away to Walsall. The 28-year-old will be hoping to get near the 46 appearances he made for Barcelona last season, providing he can prove his worth to Mourinho.
The three-time Champions League winner had, up until this season, spent his whole career with boyhood club Barcelona. Now, the Spaniard will be hoping to prove to both his manager and himself it was the right decision moving to England.
