Both teams have had impressive performances this season, with Barcelona leading the way in terms of overall form. They have won eight of their last nine games and have scored 48 goals in their 19 matches so far. On the other hand, Real Madrid has also been performing well, winning seven of their last ten games and scoring 47 goals in 19 matches.

One reason why Real Madrid is ahead of Barcelona in goal difference is that they have conceded fewer goals than their opponents.

This means that Real Madrid has kept more clean sheets than their rivals, which is crucial in maintaining their lead in the table.

Another factor that may be contributing to Real Madrid's lead is their superior defensive record. Their defense has only conceded four goals in their last five matches, compared to Barcelona's six goals conceded in their last five matches. This has helped them maintain a solid lead at the top of the table.

In conclusion, Real Madrid and Barcelona have tied for second place in the Spanish league with equal points, but Real Madrid leads in goal difference. While Barcelona has performed well this season, Real Madrid's superior defensive record and goal difference have helped them maintain their position at the top of the table. It will be interesting to see how these two teams perform in the remaining matches of the season as they continue to battle it out for the title.
