The American has started just four games in all competitions so far this season and only one since October as he struggles to shake the hamstring complaint.
The Blues boss described the Pulisic as having ‘a tiny bit of awareness’ in his hamstring, which is why he sat out of the Champions League tie with Krasnodar on Tuesdy.
‘We’re the same as we were in midweek Hakim Ziyech and Callum [Hudson-Odoi] are out for around a couple of weeks,’ Lampard told a press conference of the team news for Everton.
‘Christian Pulisic had a tiny bit of awareness off the back of the Leeds game [last weekend] in one of his hamstrings, but he’s training normally, so we should be as we were.
‘If the game had been a different type of game it might have been a game where I would have used him, we know his abilities, that’s very clear, he showed them when he came on against Leeds last week.
‘I just have to find the way to get the best out of him regularly and consistently.’
Ziyech and Hudson-Odoi are both out of action with hamstring injuries and will miss the trip to Everton this weekend and the game at Wolves on Tuesday.
Lampard will be hoping to have them both back for the home clash with West Ham, but that may be pushing it and the visit to Arsenal on Boxing Day could be more likely.
