Eagles captain Mitch Stringer has led the London life and is looking forward to facing his old club.
After only one full season in the professional game the lad from Barnsley was transferred to London Broncos in 2004, going on to play 29 games.
He came back north with Salford Reds and rejoined the Eagles in 2006.
“It was a bit of a shock, I was only 19 but it was all right.
“ The first year I loved it, got on well with the senior players and played every game except one when I was banned.
“There’s some good things about playing in London and some bad.
“Playing-wise it’s fantastic because the players are a real close family. But there’s not many fans, which is a shame.”
Stringer’s coach during his time at London was Tony Rae who returned as boss midway through last season.
The Challenge Cup quarter-final has all the makings of a giant-killing with London bottom of the Super League.
“Tony is a very smart coach who looks at the small things in the game,” said prop forward Stringer.
“He’ll be concentrating on London because they haven’t won too many games. He’ll concentrate on what they can do right more than what we can do.
“If London are not worried they should be; we have a very good chance of winning. They’re in the habit of losing but we’re in the habit of winning.”
Stringer hasn’t decided what his final words will be before he leads out the team at Don Valley.
“I don’t think I’ll say much. The lads will just look at each other’s eyes and we’ll be ready to play.”
