The Blues head into the game after enjoying a successful festive period in the Premier League, with Antonio Conte’s men having just secured back to back wins against Brighton and Stoke City at Stamford Bridge.
Those results have left the west London side in third place in the Premier League table as they look to try and at least keep themselves within touching distance of Manchester City at the top of the pile.
Arsenal, meanwhile, head into the game looking to bounce back to winning ways immediately following the disappointment of their 1-1 draw with West Brom on Sunday.
However, Pedro has warned his Chelsea team-mates that they are in for an incredibly difficult game against the Gunners on Wednesday night.
Speaking to Chelsea’s website, Pedro said: “It is a difficult game for us, always against Arsenal it is a really tough game.
“We will prepare very well for it and I hope for the win but it will be difficult.”
Chelsea won the title in style last season but it looks as if no one will be able to catch Manchester City at the top of the table.
The Blues will go for glory in the Champions League and will take on Barcelona in the last 16 next month.
