Watford are considering re-signing Don Cowie whose contract at Cardiff City expires at the end of this month.

The midfielder has been offered a new deal by the Bluebirds but could leave on a free transfer.

Several sides are interested in Cowie with Glasgow Rangers, Burnley, Blackburn Rovers, Huddersfield Town all reportedly interested in a move for the 31-year-old.

Cowie began his career at Ross County and made 191 appearances for the club before joining Inverness Caledonian Thistle in 2007.

He spent 18 months at Caley Thistle and impressed. He scored 12 goals in 59 league matches and earned a move to Vicarage Road in February 2009 for a nominal fee, believed to be around £50,000.

He signed a two-and-a-half year deal with the Hornets and quickly established himself as a first-team regular.

Cowie made 11 appearances in his first six months at the club and then featured 44 times in his first full season with Watford, scoring twice.

He played another 39 games during the 2010/2011 campaign before controversially leaving for Cardiff on a free transfer in July 2011.

Cowie was out on contract that summer but the Hornets believed he had a clause in his deal that entitled the club to activate another year.

However, representatives for the midfielder disagreed with Watford over the interpretation of the clause.

Cowie was then offered a new contract by Watford, which we understand would have made him one of the highest paid players at the club, but he was able to leave Vicarage Road for nothing and join former Hornets boss Malky Mackay in south Wales.

The Scottish international has made 99 appearances for Cardiff but only 22 of them came last season as he struggled to remain in the first team.
