Chelsea didn't sign Pedro to play him as a traditional striker. Instead, he was meant to play behind a center-forward, linking play and creating chances with his dribbling ability and first touch. However, with center-forward Liam Delap injured, Pedro has been forced to adapt to a new role.
Delap's injury has shifted the way Chelsea's coach, Enzo Maresca, uses Pedro. He's not getting into the right positions to score, and his shooting statistics support this. Pedro's xG (expected goals) is 1.57, indicating he's not getting into the best positions to score. He also doesn't have the instinct to be effective in his new position.
However, it's not entirely Pedro's fault. Chelsea's poor discipline has led to changes in the team that have affected Pedro's performance. In games where players have been sent off, Maresca has made wholesale changes, sacrificing attacking players and leaving Pedro without service.
Pedro's strengths lie in his passing and ability to create chances for his teammates. He's provided three assists and created four big chances, completing 164 passes across eight league games. He's also shown his versatility in playing as a number ten, coming deeper to claim the ball, and popping up in wide areas with his strong dribbling ability.
Pedro is a hard worker, winning 17 aerial duels, 45 ground duels, and possession in the final third five times. He's also made 16 recoveries, three interceptions, and five tackles, showing his willingness to do the dirty work.
To get the best out of Pedro again, Chelsea could play a traditional striker. They have another striker, Marc Guiu, who they recalled from Sunderland. Guiu's presence on the bench has given the defense something to think about, and his role could help Pedro find his rhythm again.
Chelsea shouldn't be overly concerned about Pedro's recent lack of goals or assists. Most of the factors behind his struggles have been beyond his control. If he were missing clear chances and showing signs of lost confidence, that would be a different matter.
