Chelsea manager Frank Lampard believes midfielder Hakim Ziyech adds a different quality to the team's attack.
Ziyech can play attacking midfield or from the right wing, and enjoyed remarkable success with Ajax.
He was excellent against Krasnodar in the Champions League in midweek.
And the summer signing will be hoping to show his quality for the Blues against Burnley in the Premier League, if he gets the nod to start.
Lampard told the club's website: "He was really good last night, especially considering it was his first start in months. When we brought Hakim into the club it was because I'd watched him a lot and we'd played against them [Ajax] the year before so I knew his qualities.
"He's a winger that gives us real width but also gives us the clever movements when he comes off the line.
"He can really produce important assist passes or break-the-line passes which he takes on that maybe other players don't so he brings us something certainly different to what we have in terms of style."
