Cristiano Ronaldo scores to maintain Juventus' perfect start

    Ronaldo celebrates after scoring against Frosinone.

    (CNN)Cristiano Ronaldo forgot all about his red card and tears in the Champions League as he added another goal to his Juventus tally.

    The Portuguese star broke Frosinone hearts as he scored late on against the Serie A minnows to help maintain Juve's perfect start to the season.
    The Italian giants have now won all five of their league games so far and their 100% start has them three points clear of second-placed Napoli.
      Ronaldo's effort was the third goal for his new club, following his brace in their previous league match. Federico Bernardeschi scored Juve's other goal during stoppage time in a 2-0 win.
        Ronaldo's performance against Frosinone had a feeling of redemption after his controversial dismissal against Valencia in the Champions League when he was deemed to have lashed out against defender Jeison Murillo and was subsequently sent off for violent conduct.
        All that was seemingly forgotten as CR7 posted a message on Instagram praising his side's start to the season.
        "Another important victory! Come on guys, all together!" he wrote.

        Messi responds

        Sunday was the first time since 2009 that Ronaldo and Lionel Messi both scored on the same day in different leagues.
        Much has changed since then. The pair have won a combined nine Ballon d'Or awards, nine La Liga titles and Ronaldo has moved clubs twice.
        The Argentine's effort had less of an impact than Ronaldo's at the weekend though as Barcelona dropped their first points of the new La Liga season with a frustrating 2-2 draw at home to fellow Catalans Girona.
        Messi's early effort had looked to set Barcelona on their way but the visitors responded with two goals in the second half. Barca, who played the majority of the match with 10-men after Clément Lenglet's first-half dismissal, had to rely on a late equalizer from Gerard Pique.
        Despite the result, the reigning league champions are still tied with familiar foes Real Madrid at the top of the league.
