Emery may now push to include the 23-year-old after Arsenal confirmed on Friday evening that neither Mesut Ozil nor Sead Kolasinac would travel with "further security incidents" being investigated by police following an attempted car-jacking last month.

And the Arsenal head coach is pleased to have Ceballos – who has been capped six times by Spain – among his ranks for the coming season.

"Ceballos' mind is very strong," Emery said of his compatriot.

"His mentality. Last Sunday when he received a big kick on his ankle I thought 'oh, it's broken'.

"But after, on Monday, he was training – (he said) 'I'm fine and want to train'. He is showing us every day his ambition, his hunger is big. I think we need players like this."

Emery guided Arsenal to fifth in his first season at the helm, missing out on the top four by a single point as they also lost the Europa League final to rivals Chelsea.

But as well as Ceballos, the club have signed David Luiz, Nicolas Pepe, Kieran Tierney, Gabriel Martinelli and William Saliba.

While Saliba will remain at St Etienne on a season-long loan, the rest will be hoping to have an impact over the course of the season and Emery believes this is more "his" team than the one he inherited a year ago.

"We are very happy and we are delighted with what the club did (in the transfer window)," he added.

"Also (head of football) Raul Sanllehi and (director of football) Edu were working together to find the best solutions, being competitive in the moment we can sign another player and also using the club to support us economically to do that.

"And really, really now we are going to fight strong with a big responsibility with this squad and after that we want to continue doing well."
