The match against Real Betis became Xavi's 67th one as the Barcelona coach, matching the tally of his predecessor Ronald Koeman.
Here's how their overall stats compare, with numbers provided by Transfermarkt.
Wins: Xavi 43-40 Koeman
Draws: Xavi 12-11 Koeman
Losses: Xavi 12-16 Koeman
Goals scored: Xavi 135-141 Koeman
Goals conceded: Xavi 68-77 Koeman
Trophies: Xavi 1-1 Koeman
We can see that Xavi beats Koeman in everything but goals scored. The Dutchman had Leo Messi for a whole season, though, so that may have played a role. Xavi has Robert Lewandowski, and while the Pole is a threat in the box, he's definitely not as good at creating chances for his teammates.
Another thing to note is that Koeman won the Copa del Rey while Xavi's only trophy is the Supercopa. Although we beat Real Madrid in the final to win it, Supercopa is generally regarded as a minor trophy.
At the same time, Xavi has us league leaders, something that Koeman never managed to achieve at Camp Nou.
