The Italian side have been in talks with United over a move for Belgian striker Lukaku for a number of weeks now.
United stated that they would accept an offer between 50 and 60 million Euros for the attacker, making it clear that they wouldn't budge from their asking price.
This has led Inter, who are set for a busy summer with the arrival of Antonio Conte, to look for another way to lower the forward's price.
Now, the Italians may be willing to include Ivan Perisic in a deal for Lukaku. 'Daily Mail' have reported that both sides would be keen to make the transfer happen, which would see new competition for Mauro Icardi arrive at the San Siro.
