Former Manchester United star Paul Scholes says Chelsea's inability to take points off top four rivals will be Frank Lampard's biggest concern so far.
Chelsea took the lead against Manchester City on Saturday through N'Golo Kante, but ultimately fell to a 2-1 defeat at the Etihad Stadium.
Lampard's side now sit fourth in the Premier League, and have lost against Manchester United, Manchester City and Liverpool so far this season.
Scholes says that the fact they are performing well in the games against their rivals but still dropping points will be Lampard's biggest cause of frustration.
"They keep going to these big clubs, playing really well and not winning games," Scholes told the Premier League.
"That will be frustrating for him I think, because he knows he's got quality in his team but he's missing something.
"He's definitely missing something. He went to Manchester United, everyone said Chelsea were the best team, played really well, got beat 4-0.
"Played against Liverpool, played okay I don't think they were anything great against Liverpool, got beat.
"Played against Manchester City, everyone's saying the best team, they were really good, they played well, they've lost the game. Now he has to find a way of changing that.
"There's no point coming away from these games saying you played really well but lost.
"Big teams win leagues through going to Manchester City, maybe not playing that well, but nicking a 1-0.
"Like Manchester City have done today – not played very well but they've come away winning the game.
"That will be frustrating for him, he knows he's got a good team."
With Antonio Rudiger still out injured, Scholes also stated that Fikayo Tomori and Kurt Zouma did not look comfortable on the ball against City, and don't quite fit Lampard's style yet.
And with no ability to bring in players in the summer transfer window, he believes that Chelsea lack depth in attack.
"I'd be a little bit worried about his two centre-halves, the way he wants to play are they good enough on the ball?” Scholes added.
"I think defensively they're okay but they look a bit nervous on the ball to me, which can create nerves throughout the team.
"Are they a centre-forward short? We know they're missing Eden Hazard from last year, who's a big difference we know that, he's got the quality in these big games to win them.
"[Lampard's] got a really good team, but he's got to find that way of winning in big games, and that will frustrate him for now."
