Michael Ballack is the best free transfer available, according to Goal readers

The former Germany captain is the overwhelming favourite among a list of players currently out of contract, with English striker Emile Heskey finishing second in the poll
Former Chelsea and Germany midfielder Michael Ballack is the best player available on a free transfer, according to Goal.com readers.

The 35-year-old is a free agent after his contract at Bayer Leverkusen expired, and has been linked with a move to the MLS this summer, as well as the Middle East and China.

The former Germany captain could yet retire, but his popularity definitely isn't on the wane, as he picked up a whopping 43.84 per cent of the public vote.

Coming in second in the poll was former Aston Villa striker Emile Heskey, who has been linked with a move to the Championship, but appears to be holding out for a club in the Premier League. The former England international gained 17.97% of the vote.

In third place was former Bolton man Nigel Reo-Coker, who excercised a release clause in his contract following the Trotters' relegation to the Championship. The 28-year-old picked up 8.75% of all votes.

Next came former Manchester United and City midfielder Owen Hargreaves. The Canada-born midfielder joined United from Bayern Munich in 2007, but suffered badly with recurring knee injuries which saw him miss long stretches of playing time at Old Trafford. Following his move across Manchester, the 31-year-old made four appearances for Roberto Mancini's team, scoring one goal in the League Cup. He attracted 7.9% of the vote.

Thomas Hitzlsperger picked up 6.87% of the vote after leaving Wolfsburg at the end of his contract. Der Hammer used to represent Aston Villa, and is remembered fondly for his cannon of a left-foot.

Former Chelsea and Barcelona forward Eidur Gudjohnsen came in sixth with 6.72% of the vote, after leaving AEK Athens following an unproductive season with the Greek side.

Former West Brom man Somen Tchoyi gained only 4.58% despite some impressive performances last season, including a goal against Fulham at Craven Cottage. The 29-year-old has been training with Birmingham following his release, but has not signed a contract with the club thus far.

James McFadden came second-to-last in the poll, taking 1.94% of the vote following his release from Everton after a brief spell back at Goodison Park last season.

And in last place was Papa Bouba Diop, picking up only 1.44% of the public vote. The Senegalese midfielder made 17 appearances for West Ham last year as they were promoted to the Premier League.
