Last month Tottenham allowed Sandro to return to Brazil to recover from the serious knee injury which he sustained against QPR in January.
In his absence, Spurs have suffered. Scott Parker does not offer the same mobility as the 24-year-old Brazilian, Jake Livermore remains unfancied by manager Andre Villas-Boas, while Tom Huddlestone has struggled to recover from his latest ankle injury.
With six matches of the season remaining the north London club are in danger of just missing out on Champions League football for the second successive season.
Arsenal will knock Spurs out of the top four if they beat Norwich on Saturday, but Sandro remains confident that his team-mates will secure the results that will see them return to the Champions League, where he excelled during his debut season at the club.
"We have to fight to stay in fourth place," Sandro told Globo Esporte.
"Last year was complicated. We did not classify because Chelsea were the champions of Europe.
"The Champions League is a different competition (to the Europa League). Everything the fans see is what the player feels... the entrance music, the stadia, the fans... everything is amazing.
"I made first played in the competition in 2010 when we beat AC Milan at the San Siro. We beat Inter Milan, too, and we only lost in the quarter-finals to Real Madrid.
"It was a really great experience. Hopefully the club will compete in the competition again."
