Sunday, 8 September: Leicester v Worcester (14:00 BST)
"I saw how well they were playing but also saw people dropping like flies with injury - but I never thought I would get the call-up to go.
"All the boys there were on form or have been for years and years, like Brian O'Driscoll, and I think that is why we were successful out there.
"Hopefully I can continue to work on my game and try and get myself into the initial squad for a Lions Test series."
As for his club side, London Wasps begin the new Aviva Premiership campaign against 2012 champions Harlequins at Twickenham on Saturday.
The Adams Park outfit finished in eighth place in the table last season and Wade believes the side must learn to be more clinical in games.
"As a team we are in a better place than we were last year," he said. "We had a tough season two years ago, nearly getting relegated.
"We didn't do too bad last year but we have been brought in early this year to work hard with all the new boys coming in.
"I think this year we are in a better place with some great personnel who can manage games a bit better.
"It would be great for all of us to come though and come away with some silverware."
