Messi miffed over blown lead

Lionel Messi has warned his Argentina teammates that Tuesday's Copa America clash with Uruguay is a must-win encounter after their stumbling draw with Paraguay.

The tournament favorite was left stunned on Saturday after it let a 2-0 lead slip away as Paraguay snatched a 2-2 draw with a last-gasp equalizer in Group B.

Argentina's shaky defensive display in the second half has reawakened doubts about its ability to produce a title-winning performance in Chile, where it is chasing a first major championship in 22 years.
