Dani Ceballos has endorsed the managerial credentials of Mikel Arteta, declaring that the Spaniard will be one of the world's best in the future.
Ceballos has worked under Arteta for the majority of the past two seasons while on loan at Arsenal - allowing him to see the Gunners' boss methods at close quarters.
Those two terms were a mixed bag at the Emirates with the first ending in FA Cup glory but the latter seeing the club fail to qualify for European football for the first time in 25 years.
