Gunners would have to shell-out to bring striker to Emirates Stadium.
According to the Daily Mail, if Arsenal want to sign in-form Napoli striker Edinson Cavani, they will have to fork out a staggering £91m.
The Uruguayan has a £52m release clause and would demand a five-year deal worth a minimum of £150,000-per-week.
This news may not be a huge shock to boss Arsene Wenger but would almost certainly bring any attempt to sign the Serie A hot-shot to an end.
The former Palermo man has scored an astonishing 25 goals in 23 games in all competitions this season, following 33 goals in each of the last two seasons at the San Paolo.
Arsenal relied a great deal on summer signing Olivier Giroud at the start of the campaign but have opted to hand Walcott a striking role in recent weeks, with mixed results.
Cavani saw team-mate Ezequiel Lavezzi sold to PSG and may well feel that the time may be right for a new challenge.
Napoli sit in third spot in Serie A, five points behind leaders Juventus, chiefly due to the goals Cavani has provided, which make him the top scorer in the Italian top tier.
