Manchester City defender Oleksander Zinchenko is expected to join Arsenal for around £35million at the start of next week after more positive talks on Saturday.
Personal terms are not expected to be a problem for the Ukraine international who will become Arsenal's fifth summer signing and their second from City following the £45m arrival of Gabriel Jesus.
His departure will accelerate City's bid for Brighton defender Marc Cucurella.
Arsenal manager Mikel Arteta said: 'We're still hoping to improve the team and make a few more changes.
