The whole Boca team has to marked hard to stop the ball going to Riquelme's feet, he knows all too well what to do with it," the ex-Spartak Moscow midfielder told reporters on landing in Buenos Aires.
Alex, who lifted the Copa Libertadores and Club World Cup in 2006 with Internacional, also affirmed that playing in Boca's legendary home stadium held no fear for the Brazilians.
"With all due respect to Boca, and to you guys, why can't we [take a victory]? Logically we can win. We will come on to the pitch determined to play a great game."
Alex joined the Timao in 2011 after two years in Russia, and played a key role in the club's Brasileirao victory in the last campaign.
