Which club won La Liga in the 2006-07 season on head-to-head tiebreaker?

Real Madrid won La Liga in 2006–07 on head-to-head superiority over Barcelona, even though both clubs finished level on points.

Barcelona led the table for much of the season, but Madrid improved during the closing months. On 12 May 2007, Real Madrid defeated Espanyol 4–3 after trailing 3–1 at half-time and moved into contention. Barcelona then drew 1–1 with Real Betis, allowing Madrid to take the lead.

The decisive tiebreaker came from the two league meetings between the rivals. Real Madrid drew 3–3 at Barcelona's Camp Nou, then beat Barcelona 2–0 at the Santiago Bernabéu. With identical points, Madrid therefore ranked above Barcelona under La Liga's head-to-head rule.

On the final day, Barcelona beat Gimnàstic 5–1, but Real Madrid overcame Mallorca 3–1 to secure its 30th league title. The dramatic finish is often associated with the late-season "Tamudazo" that damaged Barcelona's title hopes.
