The incredible unbeaten run that that Osasuna have been putting together since April of 2018 has been ended by Athletic Club.
The team from Pamplona went 31 league matches in a row without suffering defeat, but lost 2-1 against the team from Bilbao on Sunday afternoon.
Athletic Club came out on top in a first half where both sides had a goal ruled out for offside, with Inaki Williams scoring the only goal of the half that did count.
Raul Garcia went off injured at half time and this was a huge blow for an already-depleted Athletic Club side, with Osasuna looking to capitalise.
A typically brilliant finish from Chimy Avila saw them pull level in the 76th minute, but it took just three minutes for Athletic Club to retake the lead.
Two substitutes combined, as Inigo Lekue's fight and Kenan Kodro's finish put the visitors 2-1 up and that was how it finished.
