Chelsea great Mario Melchiot insists playmaker, Hakim Ziyech needs a consistent run of games to show his best form for the club.
The Moroccan was recalled to the starting line-up against Leeds United on Saturday, but failed to impress in the goalless draw.
Melchiot told Stadium Astro: “He doesn’t always get the opportunity. I think Frank [Lampard] understood him better, he wanted him and went after him.
“I think Ziyech is facing now what he had at the beginning at Ajax. It was kind of difficult for him to get a run going. Once he got it, he was among the top-two players in the team.
“Now in the Premier League you have many stars around you. He has to understand that.
“I think it comes down to rhythm. If you don’t play that often, when you get your opportunity you have got to grab it.
“But it can take a few games to get up to speed, so if he doesn’t get those games, it becomes really tough. I like him and I think he’s technically gifted, physically fit and understands the game well.
“At Ajax he would cross the ball so many times and there were players on the end of it. They [Chelsea] need to understand what his strengths are because if he can deliver that and really master that, it could be something special, if not then it becomes tough.
“I know he won’t like it, he’s not a player who’s used to coming off the bench. He was a starting player every time at Ajax.”
