Barcelona head coach Ronald Koeman said the club must be realistic about their title chances in LaLiga.

Koeman's Barca are second and five points adrift of LaLiga leaders Atletico Madrid, who have a match in hand, through 25 rounds ahead of Saturday's trip to Osasuna.

Barca – into next month's Copa del Rey final as they look to overturn a 4-1 deficit against Paris Saint-Germain in the Champions League last 16 – have struggled to convince this season.

While Koeman played down talk of the title, the Dutchman knows Barca have a chance to end the season on a high in the Copa final against Athletic Bilbao on April 17.

"As the coach and the players we have to be more realistic," Koeman told reporters. "We cannot change our minds and opinions about the team's chances to win something all the time.

"We know we have the [Copa del Rey] final and have a chance to win a big trophy in Spain. And depending on the results of the team we can fight for the title.

"We're several points behind Atletico Madrid and we can't lose any more points because then our objective will change and that's difficult.

"Hopefully at the end of the season we can say that, despite some problems, we have done well and that we have won a title. And that would be great."

Barcelona are undefeated in their last 15 games in LaLiga (W12 D3) – the second best current run of any team in the top five European leagues, only behind Premier League leaders Manchester City (19).

Lionel Messi has scored 19 goals in 23 LaLiga appearances this season and the six-time Ballon d'Or winner could reach 20 goals in a 13th consecutive campaign in the competition – a record.

Barca captain Messi has scored 23 goals in 19 LaLiga appearances against Osasuna, netting three braces in his last five games against them at El Sadar in the league.
