United's fans left the ground singing Wayne Rooney's name after his second half double gave the English Premiership leaders victory. Earlier a wonder display by Milan's Brazilian forward Kaka had put the Italian side firmly in the driving seat, giving them a 2-1 interval lead. Rooney's stoppage-time strike gave Manchester United a 3-2 win. Trailing at the break as their defensive frailties finally caught up with them, there appeared to be no way back for a United side playing second fiddle to brilliant Brazilian Kaka. But amid the debate over who is currently the world's best between Kaka and Cristiano Ronaldo, England's young genius forced himself back onto centre stage, driving the Red Devils level when he darted onto Paul Scholes' inspired pass before drilling home a superb injury-time effort after Ryan Giggs had led a late charge forward. It leaves Sir Alex Ferguson's men just needing to avoid defeat in the San Siro next Wednesday to confirm an all-English final in Athens on May Manchester police had increased patrols for the match after trouble marred United's last two European ties against Italian opposition but there was no sign of trouble in or around the stadium.
