Chelsea are devising a new training programme for Christian Pulisic.
The club is being cautious over the American’s fitness issues given his past injury records.
In his debut season for the Blues, Pulisic fired 11 goals and laid on nine assists and became the youngest Chelsea player to score a hat trick in the Premier League.
The 22-year old suffered a hamstring injury in the FA Cup final defeat to Arsenal and the club is concerned over his fitness record.
Chelsea boss Lampard said: “There is always a concern about players’ fitness when the history says there has been some injuries and last season we did have it with Christian.
“I was questioned many times on my position on Christian when he did play and didn’t play.
“Of course, when you look at a player with his recent record, you are trying to find the right way, the right balance of getting the best out of him which we saw in big periods last year and making sure you don’t overcook him and leave him susceptible to injury, particularly a player of his explosive pace and balance. That’s a fine line.
“We are working on that and Christian is also very open to that.
“He wants to play, he is so hungry to play and he is very nearly fit now but it is certainly something we will have to manage with him this season because we have all seen the talent and it is something we want to get right.
“I am not saying it is a fundamental chronic issue, it’s not. But we want to get as many minutes of the really great Christian we saw lots of last season on the pitch.”
