Juventus veteran striker Alessandro Del Piero is doubtful for his side's Champions League match against Arsenal on Tuesday due to a thigh injury, coach Fabio Capello said. The Italian international picked up the injury during his side's 1-1 draw with AS Roma in the Serie A on Saturday. Del Piero's injury in his left thigh is similar to another right-thigh injury that sidelined him from training last week. Juventus travel to London to play Arsenal in the first-leg of the quarter-finals, already missing Czech playmaker Pavel Nedved because of suspension. French international David Trezeguet and Swede Zlatan Ibrahimovic are likely to start at Highbury while Uruguayan forward Marcello Zalayeta will be on the bench.
