Fresh faces make up much of the roster for the final Canadian women’s national team camp before February’s Olympic qualifiers, but the youngsters will have to prove they can handle the pressure to join the team on the road to Rio.

“When you get closer to an Olympic qualification (with) a lot more on the line, can these younger players still manage that weight? This is where we learn a bit more,” head coach John Herdman said Monday from Vancouver, days after 23 players assembled to start their preparations for another Games. The Canadians won a bronze medal in London four years ago.

The latest roster, announced Friday, is significantly changed from the squad that represented Canada at the Women’s World Cup only seven months ago.

Gone, for now, are defenders Robyn Gayle, Emily Zurrer, Lauren Sesselmann and Carmelina Moscato, midfielders Kaylyn Kyle and Selenia Iachelli, strikers Adriana Leon and Jonelle Filigno, and recently retired goalkeeper Karina LeBlanc.

In their place come goalkeeper Sabrina D’Angelo, defenders Kennedy Faulknor, Rebecca Quinn and Shelina Zadorsky, midfielder Deanne Rose, and strikers Janine Beckie, Gabrielle Carle, Marie Levasseur and Nichelle Prince.

Faulknor, Canada Soccer’s under-17 female player of the year for 2015, and Rose are the youngest of the rookies at 16 years old, while Zadorsky is the “veteran” newbie at age 23.

“We’re building connection here, we’re working on some of the tactical frameworks,” Herdman said of the mixed group in camp, “But at the same time we’re getting a clear heads-up on two or three players, whether they’re the ones that will, when called up, provide us with what we need to move through to Rio.”

If the youngsters can’t provide Herdman with that proof, he can still bring back some of the familiar faces from last summer’s tournament.

On Monday, Canada had to provide CONCACAF with a pool of 35 names from which its team will be selected for the Houston-based qualifiers. Only 20 players will go to the tournament.

Canada will face Guyana, Trinidad and Tobago and Guatemala in the group stage of the qualifiers, which begins Feb. 10. Only two teams of eight will earn a spot at Rio in August.

While Canada is ranked 37 places ahead of its nearest group stage competitor, Herdman said the team will not underestimate anyone.

“This team is well aware there are no guarantees. If they don’t perform, they might not see Rio this year.”
