Allegri anxious to keep Juve in the groove

TURIN, ITALY - Striking a balance between scoring more while shoring up its defense will be the key if Juventus is to avoid another Champions League quarterfinal exit after cruising past Porto and into the last eight, coach Massimiliano Allegri said on Tuesday.

Juve put one foot into the quarterfinals of Europe's premier club competition last month with a 2-0 win at 10-man Porto.

The Turin giant was impervious on its way to stretching its unbeaten run in Europe to 21 games, despite failing to build on its numerical superiority after Porto lost a man before halftime.
