#1 Using Samuel Eto'o as a makeweight to sign Zlatan Ibrahimovic
Once upon a time before Lionel Messi held sway at Barcelona, a certain Cameroonian by the name of Samuel Eto'o was the club's go-to man in terms of getting goals.
Samuel Eto'o banged in goals for fun during his six year stay at Nou Camp, scoring over 100 goals at the club and becoming the highest appearing African in history in La Liga.
In his prime, Eto'o was considered as one of the best strikers in the world, winning the Spanish Golden Boot on one occasion as well as making a podium finish at the FIFA World Best award as well as the African Player of the Year a record four times.
He helped guide Barcelona to two Champions League final victories, scoring in both finals as well as three La Liga trophies and he played his way into Barcelona greatness with his goal scoring displays.
At about the same time, a certain Swede in the name of Zlatan Ibrahimovic was also making headlines with his displays in Italy with Inter MIlan and Juventus. However, for all his wonderful performances, it still came as a major surprise when Pep Guardiola snactioned the purchase of Ibrahimovic from Inter Milan in the summer of 2009 in a deal worth €66m, with Barca paying the Italians the sum of €46m added to Samuel Eto'o.
So in essence, Samuel Eto'o was offered to Inter for just €20m, which was rather ridiculous considering Eto's abilities and the fact that he was just 28-years-old at the time (just a year older than Ibrahimovic).
To further highlight the ludicrousness of the deal, Zlatan left the Nou Camp for AC Milan just a season later, while Eto's helped Inter win a treble in the same time (eliminating Barcelona along the way in the UCL).
