Barcelona could make history in its Spanish league match Thursday against Rayo Vallecano.

Barca is looking to extend its 2015-16 unbeaten streak, in all competitions, to 35 games, the longest in Spanish soccer history. They tied the current record, set by Real Madrid in 1988-89, over the weekend after defeating Sevilla FC. Interestingly, Sevilla was the last team to defeat Barcelona — almost five months ago, in October 2015.

Nearly 80,000 fans turned up Sunday at Camp Nou to watch the historic victory, which included goals by Lionel Messi and Gerard Piqué.

While Barcelona looks set to establish a new Spanish record, how does their achievement compare to Europe's best?

Steaua Bucureşti - 106 Games (Europe's all-time highest unbeaten streak)

In the 1980's this legendary Romanian side won five straight titles before finally being dethroned by Dinamo Bucuresti in 1989-90.  

Bayern Munich - 53 Games

One of the best in recent soccer history, Bayern's domestic streak in 2013-14 came to an end following a 1-0 defeat to Augsburg.

Arsenal - 49 Games

The Gunners famously went the entire 2003-04 Premier League season undefeated — earning the nickname "The Invincibles."

AC Milan - 58 Games

Labelled "The Immortals," these Italian giants were undefeated from 1991-93, the best domestic streak in Serie A history.
