The La Liga champions under Diego Simeone last term are reportedly prepared to offer Benfica former Liverpool full-back Emilio Insua as a bargaining chip in their proposed deal to sign Gaitan this summer.
Atletico Madrid have reportedly already opened initial negotiations with Benfica over a deal for Gaitan and Benfica are understood to be open to a part-exchange deal letting Nicolas Gaitan leave and bring Emilio Insua in.
Insua managed just five starts for Ateltico Madrid last season and is understood to be considered surplus to requirements in the Spanish capital where he moved just last year from Sporting CP in Portugal after leaving Liverpool In 2011.
The 25-year-old left-back is a national team colleague of Gaitan’s with Argentina although neither player made it onto the pitch at the World Cup this summer.
Whilst Manchester United may have the cash to spend this summer following their announcement of a £750 million record-breaking sponsorship deal with Adidas, in this case, money might not be the only this Benfica are after.
