RIO DE JANEIRO (Reuters) - Gremio midfielder Luan was a surprise inclusion in the Brazil squad announced on Thursday for upcoming World Cup qualifiers against Ecuador and Colombia.
A reported target of Arsenal and Liverpool, the 24-year's only previous appearance was as a substitute in the January friendly against Colombia, when coach Tite picked only home-based players.
"He is a player that had a great Olympics and he was always on our radar," Tite said of Luan, whose midfield promptings helped Brazil win the Olympic soccer gold last year for the first time. "He is a principal link up player and deserves to be called up."
Corinthians goalkeeper Cassio was the other surprise inclusion.
The big keeper has been outstanding in the Corinthians' rise to the top of the league and is well-known to Tite from when he led the Sao Paulo side to the Copa Libertadores in 2012.
Top of the South American table, Brazil have already qualified for Russia 2018 and have won all eight of their qualifiers since Tite took over in the middle of last year.
They play Ecuador at home on Aug 31 before flying to Colombia to face the home side on Sept. 5.
The top four in the South American section qualify automatically for Russia. The fifth-place side goes into a play-off with a team from the Oceania confederation.
