Barcelona coach Ronald Koeman says he will take an interest in Sunday's Madrid derby but is unfazed by the result as the LaLiga title race heats up.

The Catalans defeated Osasuna 2-0 on Saturday to extend their unbeaten LaLiga run to 16 matches and close to within two points of leaders Atletico Madrid, who have two games in hand.

One of those is Sunday's Madrid derby where third-placed Real Madrid will also look to close within two points of Atletico with victory.

Atletico have wavered in recent matches, dropping points in three of their past five, opening the door for Barca and Madrid, although Koeman said he would be unfazed by the outcome.

"The derby in Madrid? The most important thing is our result," Koeman said.

"But of course we're interested in it. Any result would be good."

Jordi Alba and Guinea-born 18-year-old midfielder Ilaix Moriba netted the goals in Saturday's win at Osasuna.

The teenager was making just his third appearance in LaLiga, having come through Barcelona's famed academy.

"Ilaix is young, but is physically very strong," Koeman said. "He's gaining ground to be with the first team more often."

He added: "Ilaix scored a goal in a difficult match, with 0-2 we killed off the game. Every time Moriba enters the pitch he brings something extra.

"Players like Pedri, Ilaix, Riqui [Puig], [Ronald] Araujo and [Oscar] Mingueza are the future of the club.

"We're proud to be able to bring in young homegrown players. But we are not doing it because the fans want it, we're doing it because they deserve it."

French defender Samuel Umtiti was replaced at half-time by attacker Ousmane Dembele, a switch Koeman clarified.

"The substitution of Umtiti was tactical. We wanted to be in better control," he said.

"It's true he had a card but he wasn't applying pressure well. We improved in the second half."
