Real Madrid is the lone perfect team left in Spain's La Liga after four matches of the new season.
The defending Spanish and European champions are still on maximum points after a narrow 2-1 win over a spirited Real Betis side on Saturday.
Betis saw its own perfect record spoiled by the loss, which was decided by a Rodrygo goal in the 65th minute after the teams exchanged goals in the first half.
Second-half sub Fede Valverde helped create the goal just one minute after coming into the match, serving up his Brazilian teammate for the winner.
The visitors started the match well, but after they were denied on a penalty shout, they conceded the opener to Real Madrid's Vinicius Jr.
The Brazilian star beat the offside trap to run onto a ball over the top, and his control and lofted shot over the 'keeper were exquisite,
winning the applause of a loud Santiago Bernabeu crowd eager to see its team again after over 100 days since the last home match.
