Clive Allen hopes his reserve side transfer their form from Lille to Leyton Orient when they face Portsmouth on Tuesday night.
After losing narrowly at West Ham in their last competitive fixture, development coach Clive led Under-18 and Under-21 teams to France on Wednesday.
The Under-18s drew 1-1 while the Under-21s, many of whom will be involved against Pompey, toppled Lille 2-1 with goals from Jacques Maghoma and Jon Obika.
"It worked very well in Lille," reflected Clive back at Spurs Lodge. "It was a great experience, we took 30 players for the two games and for some it would have been a first experience of travelling abroad and facing European opposition.
"It was a test and both games were well contested. I concentrated on the Under-21s and we came up against a technically very sound Lille team, very competent on the ball and they caused us some problems which I'm pleased to say we overcame.
"Having gone 1-0 down we got ourselves back into the game and led 2-1 at half-time, a lead we held on to.
"The lads will have learned a great deal from the experience and the occasions we've travelled away for games like this have proved very beneficial. It's great for the lads' education."
Pompey are next for Clive's men with a 7pm kick-off at Brisbane Road.
"We've had some good performances particularly against Chelsea and Arsenal and haven't got the results we perhaps deserved but it wasn't the best display against West Ham, although we could have got something out of the game," he added.
"We have to maintain the level of performance we're striving for and get the right result.
"Portsmouth can line-up strong, Harry Redknapp has a big squad and sometimes he doesn't field any first team squad players, other times he does.
"I expect a tough game and it will be difficult but were looking for a performance and positive result."
