Karim Benzema is being monitored by Louis van Gaal as a possible summer addition for Manchester United.
Benzema is viewed as a potential solution for United's goalscoring issues.
Arsenal would also likely bid on Benzema if he becomes available with the cost approaching £40 million.
United goalkeeper David De Gea, who is valued at up to £30 million, could well be used as a makeweight in any deal.
Benzema is 27 and considered to be at his peak.
