Motherwell midfielder Stephen Hughes believes they must focus on hitting peak form against Nancy rather than worry about conceding away goals.
Hughes is the most experienced player at Fir Park in terms of European competition, with Thursday night's UEFA Cup first-round second-leg clash his 13th at that level.
The former Rangers midfielder also has experience of turning around the 1-0 deficit Motherwell face - he played at Ibrox when Portuguese side Maritimo were beaten on penalties after a 1-0 victory for the Gers in 2004.

So he knows there is no way Motherwell can attack with abandon - but he insists the vital factor is being on their game.
The 25-year-old said: "You don't want to go gung-ho and leave yourself vulnerable at the back and they sneak that goal which would be vital to them.
"But at the same time, we need to go and attack because we need to win the game. It will be interesting.
"The manager I'm sure will have his system, but the most important thing is we go out and perform on the night. If we do that, we have a chance of going through.
"They are a good team, they showed that over there. But they are beatable and if we play the way we played last season then we have a really good chance."
Well failed to land a shot on target in the Stade Marcel Picot but the players did not look comfortable in their 4-5-1 formation, and Hughes is confident they will be much-improved.
"We have still come back with a result that gives us a great chance here," he said.
"That game is in the past, we just look forward to making amends by winning the game and hopefully putting ourselves through.
"Everybody has been buzzing all week. We can't wait to go out there and try to get the result we need."
Hughes missed Saturday's 2-1 win over St Mirren after picking up a minor knock.
A hamstring injury in August prevented him joining up with the Scotland squad, while a calf knock forced him to miss several days' training before the first leg.
A fit Hughes is a crucial component in linking Motherwell's midfield and strikeforce and he is eager to drive on.
"It was my knee I had problems with but I'll be fit," he said.
"I've had a few niggles, which is never nice, because you obviously you want a run of games.
"Hopefully I can put them behind me and look forward to the season ahead, starting with the Nancy game."

We guarantee this bet
It's understandable that some people will not believe that it is possible to do this. "What's the catch?" I hear you asking. My answer to that question is that this is the fifth season that we have been publishing arbitrage bets and literally hundreds of people have profited from following the advice on these pages.
Only twice has our refund guarantee been triggered and that was when we did all the figures wrong and sent refunds out to those who had followed our advice and made a small loss.
Our refund guarantee works like this. If this bet doesn't work like we say it will and you end up out of pocket, we will refund your losses. Simple as that.
That means that you simply cannot lose on this, whatever happens and even if we messed up the numbers.
The only stipulation here is that you must click on the links on this page to be eligible for the refund guarantee, not that you'll be needing to claim anyway. Just enjoy the profit and stay posted for many more of these throughout the season.
