Bournemouth boss Andoni Iraola admits he's still getting used to handling bigger budgets.
Iraola moved to Bournemouth from Rayo Vallecano over the summer.
He told Marca: "In England an average player, who you don't know if he is going to start, costs 15 million. In Spain, if you spend that on a footballer, it has to be differential.
"My most expensive signing until I arrived at Bournemouth was De Tomás (€8m) and here they consider that figure low. This causes the internal market to inflate compared to the external one."
Iraola added, "As a player I had not been able to play in the Premier League and he has always caught my attention. It is the greatest challenge to face the best footballers and coaches.
"I'm happy with my decision."
