Christian Pulisic and Timo Werner must improve despite Chelsea's return to winning ways in the Premier League.
That's according to Sky Sports pundit Jamie Redknapp, who picked out the Blues duo following their 1-0 win over Fulham in the west London derby at Craven Cottage on Saturday evening.
Whilst Werner ended his 12-game goal drought in last weekend's FA Cup third-round win over Morecambe, he wasted a glorious chance to make it 2-0 in injury time against Fulham.
As for Pulisic, he's yet to hit top form in what has once again been an injury-disrupted season for the USA international.
Interestingly, Pulisic played the whole 90 minutes, but Werner was named among the Chelsea substitutes and came on after 74 minutes for Olivier Giroud.
But Redknapp is of the opinion that the Blues' recent signings are not doing enough to show head coach Frank Lampard that they are worthy of a starting place.
"There's no doubt at all, it’s tough at times," Redknapp said. "He must spend hours in his dressing room at Cobham, looking at how he’s gonna set the team out, the system he is gonna play, looking at how he can keep everyone happy.
"It's the most difficult thing in the world when you’re a manager, you’re always gonna have players that aren’t playing, especially when you're not winning.
"But the problem is, you don’t wanna stop the young players developing as well.
"I’m sure if you're Mason Mount this summer, and he sees Ziyech coming in and the likes of Havertz, he thinks, ‘where am I gonna fit in?', it’s difficult.
"It can take a knock on your confidence, but right now, it’s the younger players leading the way.
"I wanna see more from Pulisic, Werner hasn’t done it yet.
"His confidence is rock-bottom, he needs something to go in."
Redknapp's observation could leave Lampard with a major team selection decision for next week's clash against Leicester City as Pulisic's place may be at risk.
