Alexandre Lacazette is set to finalise his move from Lyon to Arsenal after completing a medical at the Gunners' training ground on Tuesday, Sky sources understand.
Lacazette is expected to sign a five-year deal at the Emirates Stadium after Arsenal agreed a club-record deal with the Ligue 1 side which could rise to £52m over the course of his contract.
'Lacazette may persuade Sanchez'
Nigel Winterburn believes Alexandre Lacazette's imminent arrival at Arsenal may influence Alexis Sanchez...
The France international, who has agreed personal terms, had verbally agreed to join Atletico Madrid this summer but that deal collapsed last month after Atletico's transfer ban was confirmed by the Court of Arbitration for Sport.
Arsenal's opening bid of £39m was turned down last month, but Lyon president Jean-Michel Aulas had confirmed a deal was likely to be completed after the sides met on a fee that would eclipse the £42.5m Arsenal paid for Mesut Ozil four years ago.
Is Lacazette the answer?
Lyon have confirmed a move is imminent but can Lacazette fire Arsenal back up the table?
Lacazette had said he would only move to a club who are playing in Europe's premier club competition but it appears the 26-year-old's stance on the matter has softened.
He boasted the highest chance conversion rate in Europe's top five leagues last season (38.9 per cent).
His record of 28 league goals last term was more than the combined tally of Arsenal quartet Olivier Giroud, Theo Walcott, Danny Welbeck and Lucas Perez.
