Europa League-bound Arsenal have signed Real Madrid midfielder Dani Ceballos on a season-long loan deal.

The 22-year-old has made 56 appearances for the Spanish giants since joining in 2017 from Real Betis.

Arsenal are also set to sign 18-year-old Saint-Etienne centre-back William Saliba, who is expected to cost about £27m.

The France youth international will return to the Ligue 1 club on loan next season before joining up with the Gunners in 2020.

Saliba has expressed a desire to join Arsenal despite late interest from Tottenham.

Ceballos will wear the number eight shirt this season and could make his debut against Lyon in the Emirates Cup on Sunday.
