Six Nations: France vs Scotland

Gregor Townsend is optimistic the attacking instincts of the Evans brothers can help Scotland defeat France.

The Glasgow pair, centre Max and winger Thom, have been brought into the side for tomorrow's RBS 6 Nations clash less than a month after helping their club side beat Heineken Cup favourites Toulouse 33-26.

Their introduction has taken the Glasgow contingent to seven, and they will come up against six Toulouse players at the Stade de France.

And Edinburgh's victory at Castres, Townsend's former club, earlier in the season has given Townsend further hope that the players can bounce back from their disappointing defeat to Wales on Sunday.

During his playing days, Townsend was a key component in two rare Scotland victories in France, including the last one, a 36-22 triumph in the Stade de France in 1999.

And he senses that the current crop of internationals appreciate that Scotland must be positive against Marc Lievremont's team.

"This year a Scottish side won in France in the Heineken Cup for the first time, Edinburgh first and then Glasgow," Townsend said.

"Edinburgh beat Castres home and away and Glasgow beat Toulouse. Those players know what it's like to win in France and they know what is necessary to win in France.

"You must attack the French, you have got to move them about, you have got to play rugby and be ambitious.

"Glasgow were certainly ambitious against Toulouse and it paid off because they were very accurate. Players like Max and Thom really had great games.

"Edinburgh were very similar, they really put pace on the ball and scored a couple of tries. Castres came back into it but they held on.

"Most of our players are from Edinburgh and Glasgow and they know that's what they have to take in tomorrow."

The Evans brothers have both been promoted by Frank Hadden following a clamour from Scottish rugby fans.

Max came off the bench to spark a late revival and score Scotland's only try in their 26-13 defeat to Wales.

His younger brother Thom has scored nine tries for Glasgow this season and Townsend believes they will add fresh impetus to the national team.

"Both are really keen to learn and have been in top form this season," the 35-year-old said.

"I think they are really enjoying being in the Test-match environment.

"You can tell from Max's performance at the weekend just how much he loves getting his hands on the ball against a quality defence, which only gave away two tries last season.

"They have been on fire this week. It helps that Thom and Max didn't play much rugby last week, so they have been buzzing from the beginning of the week.

"They are positive people. They are always impressive in training. We have a lot of ability in our back line but when you see Thom catching kicks that you think will never reach the winger's hands, it's great for the coaches and players."
