Frank Lampard admits it is “difficult” to get Hakim Ziyech match fit and “integrated” because of Chelsea’s coronavirus bubble.

The Morocco international was injured during a preseason match and has not been able to recover his form ever since.

Lampard says it has been difficult to get him up to full fitness because he hasn’t been able to put on training matches with the younger players due to bubble restrictions at Cobham, so he has to get sharper in games.

He said: “It’s been very difficult to integrate him.

“We have a bubble here at Cobham so we can’t play against the Under-23s or bring over a lot of kids to replicate 11 vs 11 games on big-sized pitches, which is generally where you would want someone to be working when they’ve not played for five or six months off.

“We miss that and we have to find the right way to give Hakim and others in the squad minutes as quickly as we can.”
