The American winger has not played since October 31 due to a hamstring issue, a problem which also ended his appearance in the FA Cup back in August.
Pulisic will miss Saturday’s clash with Newcastle United and Lampard wants to find a solution for his injury problems, insisting that the 22-year-old still has a big future at Stamford Bridge.
“With Christian, we’re still searching,” said Lampard. “He’s in a position at the moment where he’s had a problematic injury.
“Christian had a history before coming to us of some muscular injuries and he’s had them again.
“Everything about Christian and how he is around the training ground, and how he prepares and how much he wants to play, is perfect.
“We need to try to find the right balance between playing and resting and maintenance during the week to try to get the best out of him.
“He’s a young player still. It’s not abnormal and we will find a solution. I don’t want to make more of it than it is, because we want as many games out of Christian as we can possibly get because of his ability.
“But at the minute he’s injured so in the short term it’s a work in progress.
“But we have a great medical team here and we’re very much joined up in the idea of getting the best of Christian, to get him fit as much as we can.”
