He was part of the management team which tasted European success by lifting the Heineken Cup 2007 and after his appointment, replacing Tony Hanks at the helm of the club earlier this year, Holden has targeted more European glory in the form of the Amlin Challenge Cup.
"I am settling in really well. It's been great," he said.
"My main objectives are, quite simply, to make Wasps the best that we can be.
"We are still in a major Cup competition and a big aim for all of us will be to be successful in the Amlin Challenge Cup.
"Reaching the Premiership play-offs is still a target obviously and I am keen to improve upon recent results.
"Everyone has been welcoming and it is really nice to be back among old workmates and everyone who is new to the club, who have been doing a really good job.
"I didn't really have any hesitations at all about coming back here. I used to always think of the club and people I had worked with when I was here before.
"I really enjoyed my time here when I was last in London and so it was not really a tough decision for me to come back. I was honoured to be asked to help out."
