Juventus recently suffered defeat in the hands of Barcelona 3-1 in the Champions League Final but they are looking to have a busy offseason and already completed the transfer of Croatian forward Mario Mandžukić.

Mandžukić completed a medical at Turin Monday joining Juventus for a three-year deal with an option for a fourth year and he is set to earn €15 million with €3 million in add-ons.

"I like Juventus and I like the city [Turin]. I hope I will be happy here. I will fight for my new team," the 29-year-old said according to BBC Sports.

Mandžukić was from Atlético Madrid whom he joined last summer from Bayern Munich and played in 43 games scoring 20 goals.

The move was the third time in four years that Mandžukić transferred to a club which just lost in the Champions League Final after his move to Bayern in 2012, last summer's transfer to Atlético and the recent move to Juventus, BBC Sports reported.

Juventus is eyeing Mandžukić as a replacement for forward Carlos Tevez who is reportedly leaving to return to his first professional club the Boca Juniors back in his native Argentina.

The 31-year-old was Juve's leading scorer in the past two seasons and still has one year remaining in his pact with the club.

Tevez played efficiently last season and helped Juventus nearly complete a treble as they won the Serie A and Coppa Italia titles but were unsuccessful against Barcelona in the Champions League Final.

In a report by ESPN FC, Boca are hoping they could come up with a deal by Wednesday to sign Tevez.

Meanwhile Atlético looks to replace Mandžukić with Villarreal forward Luciano Vietto, The Guardian reported.

Villareal president Fernando Roig was quoted by The Daily Astorian saying that Vietto was already sold to Atlético.

But a spokesperson for Atlético said there is no final deal yet for the 21-year-old Argentine forward.
