The Argentina international has warned his team-mates to be wary of the prolific striker when his country meet Colombia in Friday's World Cup qualifierArgentina star Javier Mascherano has praised Colombia forward Radamel Falcao, labelling him as "one of the most important strikers in the world".
The two nations are set to meet in World Cup qualifying on Friday with Argentina leading the Conmebol on 24 points while Colombia in third place on 19 points with a game less played.
Mascherano has warned his side against the threat of Falcao, whom he came up against in La Liga when the former Atletico Madrid striker played against Barcelona.
"Falcao is one of the most important strikers in the world. He has improved a lot in the last three or four years," the 28-year-old told reporters.
"His improvement has been something out of this world. In the national team we have players that know him well, like [on loan Getafe defender] Federico Fernandez, [Inter's] Hugo Campagnaro and [Benfica's] Ezequiel Garay.
"[Colombia coach Jose] Pekerman has built a team with players around Falcao, so we will have to dismantle their offensive rhythm."
Falcao recently joined newly-promoted Ligue 1 side Monaco for €60 million after netting 34 goals this season.
