(CNN) Amid rape allegations and with growing unease among his sponsors, Cristiano Ronaldo appeared unaffected as he starred for his club Juventus in its latest win.

He scored the second goal in Juve's 2-0 win at Udinese, the 10th win in a row in all competitions since the start of the season for the Serie A giant.

It was Ronaldo's fourth goal for his new club since his move from Real Madrid in the summer, and he was afforded a rapturous reception by Juve fans, who chanted "Cristiano, Cristiano," as he left the dressing room following Saturday's evening's game. It was his first match since the allegations became public.

"Way to go, altogether," he later tweeted on his own personal account, retweeted by the Juventus official account.
