Chelsea suffered a surprise 1-0 defeat to Kawasaki Frontale in their third pre-season match as they continue preparations for the upcoming Premier League campaign.
In hot, humid conditions, the Europa League winners created few clear-cut chances and were made to pay, when Leandro Damiao headed in on 88 minutes.
Chelsea Lampard, who would have been pleased his players got more minutes under their belts, but ultimately disappointed with a loss.
When these games are not necessarily indicative of what lies ahead, it showed there is still much for Chelsea to work on, while there were moments of promise.
talkSPORT.com takes a look at five things we learned from the Yokohama friendly.
Lack of goal threat
Hazard has left Chelsea with a massive void that will struggle to fill any time soon.
In his final season, the Belgian netted 21 times and assisted further 17, showing just how important and decisive he was.
In Yokohama, Chelsea lacked any real cutting edge with Michy Batshuayi starting the first-half, flashing one shot wide, and Olivier Giroud entering for the second
Tammy Abraham, who shone for Aston Villa, watched from the stands two to tonsillitis.
The fact right-back Davide Zappacosta had Chelsea's first shot on target says it all and Lampard will hope for more efficiency against Barcelona on Tuesday.
Barkley and Mount impress
Lampard is a huge fan of Mount and rewarded him with a new five-year contract.
The 20-year-old has looked impressive since returning from Derby and offered flashes of his quality against Kawasaki Frontale as he began in the No.10 role.
After the break, Barkley came up with, with one hand, and with an instant difference, with several probing passes.
Barkley's introduction gave Chelsea fresh impetus and Lampard will have been more than pleased with the performance of both men.
The Bakayoko conundrum
Tiemoue Bakayoko spent last season at Stamford Bridge.
While he took time to settle in Italy, he soon found his feet and showed much of the quality that made Chelsea buy him from Munich in 2017.
However, the Frenchman is simply not good enough to play for Chelsea.
His decision making leaves is much to be desired in the Premier League.
Coming on Mateo Kovacic, Bakayoko looked ponderous and struggled to assert, to run with the ball, which was against opposition of this caliber.
It was a first appearance in a Chelsea shirt for Christian Pulisic and made a positive contribution when he did come on.
A couple of driving runs down the left and to get the ball in the first time, it is something Chelsea fans can expect.
Zouma here to stay
Last season, Kurt Zuma spent the season on loan at Everton and at one point, it looked as if he could move from Chelsea for good.
But, the appointment of Lampard has changed that, with the manager wanting Zouma to stay put.
"In terms of Kurt Zouma, he is a very good defender for us, very good player, very good person and professional," he said.
"I want him here, simple as that. We are competitive with the center backs and have a good season at Everton and I can understand why they want him.
"He's a Chelsea player and I want him."
When there will be much sterner tests in front of him, Zouma looked more comfortable than back and will play a vital role in what will be another year.
