Chelsea are taking special care of Christian Pulisic due to his injury woes last season.
The 22-year old suffered a hamstring injury in the FA Cup final clash against Arsenal at Wembley back in August.
He is working on his way back to fitness behind the scenes at Cobham.
The USA international has been one of the standout players for the Blues last season scoring 11 goals in 34 games in all competitions.
The winger missed a majority of the games last season due to his injuries and the club is in no rush to get him back to action.
“They [Hakim Ziyech and Christian Pulisic] are both training with us now which is good news, and we hope to have them in proper match contention over the next week or two,” Frank Lampard said before Chelsea’s trip to West Bromwich Albion.
He continued: “There is always a concern about player fitness when their history shows there has been injuries, and you try to find the right way and right balance to get the best out of Christian, which we saw in big periods last year.
“You make sure you don’t over-cook him and leave him susceptible to injury, and particularly with a player of his explosive pace and balance that is a fine line.
“We are working on that and Christian is very open to that. He wants to play, he is so hungry and he is very nearly fit now but it is certainly something we will have to manage this season.
“We have all seen the talent and it is something I want to get right. I am not saying it is a fundamental, chronic issue, it is not, but we want as many minutes of the great Christian we saw last season on the pitch.”
