BELGRADE, Jan. 13 (Xinhua) -- Lyon signed Croatian defender Dejan Lovren from Dynamo Zagreb on Wednesday as the former French champions seek to reinforce their back line.

    "Starting from today, Dejan Lovren is officially a Lyon player having signed a contract with the club," said a Dynamo statement.

    The 20-year-old joins a Lyon side who are sixth in the French Ligue 1, 13 points behind leaders Bordeaux for a poor defensive record the season.
