The Dutch star has been out of action since the World Cup finals in the summer, where he tore a hamstring.
Robben could make his return against Wolfsburg in mid-January.
“That was great!” said Robben after finishing his first training session.
“I’m part of the team again, I’ve worked towards this for a long time.
“Being back out on the pitch with the lads is an indescribable feeling.
“I’m not 100 per cent yet, obviously, I still have a lot of work ahead of me.”
