Arsenal are set to beat Tottenham to the signing of teenage defender William Saliba from Saint-Etienne.
The 18-year-old France youth international will return to the Ligue 1 club next season on loan before heading to the Gunners in 2020.
Arsenal are understood to be paying 30m euros (£27m) for Saliba with the fee paid in instalments.
The Gunners are also working on a deal to take the Real Madrid midfielder Dani Ceballos on loan.
The 22-year-old would fill the gap left by the departed Aaron Ramsey.
Meanwhile, the London club are continuing their pursuit of Celtic left-back Kieran Tierney.
