Watford boss Claudio Ranieri is facing a real battle as he attempts to sign a left back this month.
The Hornets are hoping to improve their defence in January, as they have not secured a single clean sheet in the league this term.
According to The Sun, Rangers want £5million for their left back Borna Barisic, while Watford are offering £2 million.
It appears the deal for Berisic to go to Watford may be close to dead, as Rangers have sold Nathan Patterson to Everton.
That eases their financial situation, which means they can demand a higher fee for Barisic, which Watford may not want to pay.
