The west London club signed Gusto from Lyon in a £31m deal in the January transfer window before loaning him back to the French club for the remainder of the current campaign.
A month later, the 19-year-old right-back picked up a nasty hamstring injury which saw him head to England early to speed up his recovery.
But Gusto has since completed his rehabilitation at Chelsea’s Cobham training base in Surrey and has returned to France to see out his loan spell.
Gusto made his return for Lyon during the Ligue 1 clash against Marseille on Sunday, featuring for 10 minutes.
‘It was a complicated period with my injury but I’m happy to be back on the pitch,’ Gusto said.
‘The injury was more serious than what the diagnosis suggested. I was able to recover well and that is the most important thing for both clubs.
‘Lyon and Chelsea managed the thing well in terms of my rehabilitation. It went well, I am happy.
‘There are regular exchanges with the two clubs and I had things to respect on each side.
‘We reached an agreement after a certain time. Lyon came to see me at Chelsea, to see how I was doing and It made me happy and it pushed me.’
Lyon boss Laurent Blanc, however, seemed to hint at a disagreement between his club and Chelsea’s medical staff over Gusto’s injury.
‘When two medical staff take care of a player and both agree, that can do it,’ Blanc said. ‘But if they don’t [and] are not quite in agreement, how do we do it? That’s it. It’s a special case.’
Gusto also appeared to face some criticism from Lyon supporters over heading to England for his recovery and has sent a message to them.
‘When you give everything for a jersey (Lyon) and you’re a child of the club, it affects you,’ he added. ‘I’m here to put the club back at the top. From a personal point of view, I want to leave the club in Europe, that’s important and that’s my goal.
‘And from an even more personal point of view, I also want to pick up the pace to be ready for next season.’
Gusto will provide competition for fellow right-back Reece James at Stamford Bridge, who Frank Lampard recently revealed will miss the rest of the season.
