Lampard has been settling into life at Stamford Bridge after having been appointed as the club’s new manager in July following the departure of Maurizio Sarri to Juventus.
It has been a mixed start to the season so far for the Blues, who have only managed to take five points from their opening four Premier League games.
Their only win under Lampard this season was the 3-2 victory at Norwich City last month, and they squandered a 2-0 lead to draw 2-2 with Sheffield United at the weekend.
Chelsea FC are aiming to try and maintain their place in the top four this season after they finished third last term under Sarri.
And Barkley has now lifted the lid on what the first few weeks have been like for the Blues under Lampard at Chelsea FC.
Speaking in an interview with Chelsea FC’s website, Barkley said: “He wants us to improve and perform at the level we can perform at. He’s not too nice, he can have a go, he has a go in training when things aren’t going well.
“The positive side of things is he trusts young players. As well as developing them he is implementing a new style of play with us. The early signs are that we’re improving.
“[Saturday] isn’t going to determine where we finish at the end of the season. We’re only four league games in. We’re going to come back after the internationals and try to lead by example in training and put better performances in.
“We’re going through a bit of a development phase at the minute but we can still perform really well over the course of the season and surprise a lot of people.”
Chelsea FC will return to Premier League action after the international break when they take on Wolves away from home on Saturday 14 September.
The Blues are currently in 11th place in the Premier League table.
