Bolivia coach Gustavo Quinteros believes that his team can take something from Friday's World Cup 2014 qualifying clash against Argentina, and saw a close eye on Barcelona's Lionel Messi as the key to success.
The Andean nation currently lie bottom of the standings for Conmebol's World Cup qualifiers, starting their campaign with defeats against Uruguay and Colombia to fail to register a single point.
As the Verde prepare to visit the Monumental against their South American neighbours, Quinteros was adamant that his charges should not be written off before the game; although he admitted that a solid defensive effort would be vital.
"It is always a danger if you attack Argentina too much, if you give too much space to Higuain, Messi, Aguero of course you are going to risk more than if you play a tighter game, closing the spaces and not giving up chances," the Argentine trainer explained to La Red on Wednesday afternoon.
"If the minutes go by and they still have not hurt you, Argentina are going to come out more desperate, risking more and that is when you can take advantage."
Quinteros singled out Messi as the biggest danger to his side's chances, and urged Bolivia to control the virtuoso No. 10.
"We have to control Messi wherever he goes, without having to rely on a man-marker. The key is putting on him solid, firm, sticky marking, without bad intentions to not leave him the spaces he enjoys in Europe," the coach stated.
"When he has time on the ball it is very difficult to control him. You have to be close all the time."
Argentina and Bolivia meet on Friday in Buenos Aires, with kick-off scheduled for 21.00CET.
