Arsenal have reached an agreement in principle with Saint-Etienne to sign defender William Saliba, Sky Sports News understands.
According to Sky Sports, the deal between Arsenal and Saint-Etienne will see Saliba return to the French club on loan next season.
The deal was close to completion once before, only for Tottenham Hotspur to come in at the last minute in an attempt to hijack their north London rivals' deal.
Saliba will now put pen to paper to a five-year contract with the Gunners on Tuesday.
And Arsenal are hopeful that further new additions will follow, potentially by the end of next week - with the capture of Ceballos set to be finalised in the coming days.
Saliba is one of Europe's most highly-rated young centre-backs and signing him is a massive coup for Arsenal, whose defence is in desperate need of reinforcements.
The French teenager is now set to become Arsenal's second major signing of the summer window following the arrival of Gabriel Martinelli but it's expected to be a busy few weeks with Emery in the market for several new players.
Ceballos has not travelled with the squad, however, as he is still on holiday due to his involvement with Spain Under-21s at the European Championship earlier in the summer.
Despite being just 22-years-old, he has already won virtually everything that there is to win in Scottish football and has already previously captained both Celtic and the Scotland national team.
"Tierney on a permanent deal if they can sort out the structure of payment".
Celtic manager Neil Lennon has reportedly admitted that his star left-back Kieran Tierney is similar to former Manchester United superstar Cristiano Ronaldo and stated that he would like to keep hold of the Scotsman despite the fact that Arsenal is interested in his signature.
