Hernan Crespo considered quitting soccer after his disastrous first season at Chelsea.
The Argentine star scored Chelsea's winner as Jose Mourinho's side warmed up for the new season with a 2-1 win over DC United in Washington.
But Crespo has revealed how low he got after his first season at Stamford Bridge.
Crespo joined Chelsea under previous boss Claudio Ranieri for £16.8million in August 2003, but joined AC Milan on loan last summer after a disappointing first season in the Barclays Premiership.
The 30-year-old has been persuaded to give Chelsea a second chance under Ranieri's successor Mourinho.
"Depressed is a big word but when I finished the season I thought seriously about not playing again," said Crespo, who highlighted problems off the pitch and a lack of support from the club.
"I had personal problems. I was looking for an apartment, my English is not good.
"It was even a problem trying to use my phone because I couldn't explain what I wanted. It was a problem for me to sign a contract for a house.
"There was nobody to help me.
"And when you change your country, don't speak the language and you feel alone, it's the worst thing."
