Real Sociedad have confirmed the appointment of Jagoba Arrasate as their new head coach.

Arrasate was assistant coach under Philippe Montanier, who guided the club to fourth place in La Liga before leaving at the end of the season.

Sociedad president Jokin Aperribay has claimed that he did not consider it a risk to promote Arrasate.

"Jagoba Arrasate is going to be the next coach. He is the one to continue the strategic plan we have worked to for years," Sky Sports News quotes Aperribay as saying.

"We think we will start next season without doubts, and with a perfect knowledge of what we have.

"It is not a gamble. We want to continue the sporting path, and this was an opportune moment to do that."

Arrasate will lead the Spanish club into the qualifying rounds of the Champions League next season.
