Glen Johnson believes the 4-0 defeat at Manchester United has served as a "wake-up call" for Chelsea and Frank Lampard.
The Blues suffered a heavy defeat at Old Trafford on Sunday, with two goals from Marcus Rashford, together with strikes from Anthony Martial and Daniel James, helping the Red Devils to a big win.
But Chelsea put in a decent display against Liverpool in the UEFA Super Cup on Wednesday night, with the Blues losing out 5-4 on penalties against Jurgen Klopp's Champions League winners in Istanbul, following a 2-2 draw after extra time.
And Johnson believes that shows that his former Chelsea team-mate is on the right track as the Blues' head coach.
"It’s been a tough start to life back at Chelsea for my old team-mate Frank Lampard, but I think the heavy defeat at Old Trafford might be what was needed as a wake-up call for him and the team to realise the scale of the job they face," Johnson said, speaking to Betdaq in his role as a betdaq.com ambassador.
"Despite not getting the result they wanted, it was a much better performance against Liverpool in the Super Cup, and I don’t think Frank will be too tough on his squad as he knows he must keep them onside and get performances out of them.
"I’m confident he can get things right there in the long run. He’s a strong character, and I still fancy them to reach the top four this season which, all things considered, would be an amazing achievement for them."
And ahead of the game against Leicester City at Stamford Bridge this weekend, Johnson is backing Lampard to get his first win in a competitive fixture as Chelsea head coach.
"Frank faces my old boss Brendan Rodgers this weekend and, while I’m backing Chelsea for this one, I expect Brendan to do well for Leicester this season," he said.
"Brendan’s training methods and the way he prepares teams for a match is very similar to Jose Mourinho. Their teams might have a different style of play, but there are still comparisons there.
"I’ve heard people say Leicester can break into the top six this season, which will be tough but if anyone can do it then they can. If I had an each-way bet, I’d go for the Foxes or West Ham to do so."
