Arsenal are chasing Real Betis midfielder Dani Ceballos.

Gunners boss Arsene Wenger had Ceballos scouted at the U19 Euros as he helped Spain to victory.

The midfielder was offered new terms by Betis at the end of last season and Arsenal have been encouraged that the deal remains unsigned.

Betis president Juan Carlos Ollero admits he is frustrated by the situation.

"I do not understand the attitude of the player because it is already agreed, all the details. I do not know why his (management) firm is delaying things," said Ollero.
