The Blues are still looking for their first Premier League win of the campaign after a 4-0 loss to Manchester United on the opening weekend was followed up by a 1-1 draw with Leicester City on Sunday at Stamford Bridge.
Lampard was brought in back in July after Maurizio Sarri opted to leave Stamford Bridge to take over at Juventus.
The former England international was unable to sign new players in the summer window due to a transfer ban handed down by Fifa – although the Blues did add Christian Pulisic and Mateo Kovacic to their squad on pre-arranged deals.
Chelsea FC will be at least aiming to maintain their place in the top four this season after they finished third and won the Europa League last term.
But former Arsenal midfielder Merson has admitted that he is concerned about Chelsea FC’s ability to realistically challenge for Champions League qualification this term.
Speaking to Sky Sports, Merson said: “It is not Frank’s fault they have a transfer embargo, that is how he got the job – if Chelsea did not have one, they would have gone out and bought a forward.
“At the moment, firepower wise, I just do not think they have a cutting edge. A team who dominated those games against Man Utd and Leicester would have won them quite comfortably.
“But they just have to live with the fact they will not blow teams away as they do not have that prolific goal scorer.
“Put it this way: if Alexandre Lacazette and Pierre-Emerick Aubameyang had been playing up front for Chelsea, they would have had six points.
“And that is why I worry about Chelsea getting in the top four as when you look at who they are competing with for the top four, it is that firepower that separates them.
“It is just two games gone, but they did tire in the second half – they just needed that second goal and if they get that, they run away with it.
Mason Mount is in the team because he can play and carry his own, not because he is a nice lad and Frank likes him. He has done great and is only going to get better.”
Chelsea FC will aim to win their first Premier League game of the season on Saturday lunchtime when they travel to Norwich City in the top flight.
