Atletico Madrid suffered a major blow to their title aspirations after losing to Atletico Bilbao 2-1 on Sunday night.
Diego Simeone’s side have now won six of their last 14 league games to put their title hopes in jeopardy with Barcelona breathing down their necks.
Inigo Martinez scored a last-minute winner for Bilbao to break Atletico Madrid hearts and cut their lead at the top of the log.
Barcelona earned a vital 2-1 win over Villarreal courtesy of two brilliant goals from Antoinne Griezmann to continue their impressive form.
“The players are hungry to win another trophy,” said Koeman. “The league is closer, I don’t know how much closer, but it is. We are on a good run and if we win the six games left, we will be champions.”
