Turin, Sep 1 (IANS): Italian football champions Juventus have bolstered their midfield with the signing of Brazilian international Anderson Harnanes from traditional rivals Inter Milan on a three-year contract for 11 million euros ($12.3 million).

The club completed the deal on Monday and also announced the signing of French Under-21 midfielder Mario Lemina on a season-long loan from French Ligue 1 side Olympique Marseille.

"Juventus Football Club can confirm that an agreement has been reached with Inter Milan for the purchase of Anderson Harnanes for a fee of 11 million euros, payable in three financial years," Juventus said in a statement on Monday.

"The deal may increase by a further two million euros should certain sporting targets stipulated in the agreement be achieved before June 30, 2018."

Harnanes has played 27 matches for Brazil.

Talking about Lemina's deal, Juventus said: "A fee of 0.5 million euros paid on or before September 30 would provide Juventus with the right to purchase the player outright for a price of 9.5 million euros ($10.6 million), to be paid in two financial years."

Meanwhile, Juventus have also released midfielders Mauricio Isla and Paolo De Ceglie to Marseille on free loan moves for the 2015-16 season.

Marseille also have the option to acquire the midfielder Isla's full registration rights for a fixed price of seven million euros ($7.8 million), payable within two financial years, up until May 30, 2016.
