Barry Douglas is expected to quit Leeds United in the domestic window after strong Championship club interest, Football Insider understands.

This site revealed last Saturday that Watford have made an approach for the left-back, 31, while Blackburn Rovers are also keen.

A Leeds source has told Football Insider that the club believe Douglas will leave during the short domestic-only window running until 16 October.

The next 10 days is exclusively for Premier League-EFL or EFL-only deals, either on loan or permanent.

No transfers can take place internationally or between Premier League clubs in this period.

Douglas has been told by Leeds he is free to find a new club after being frozen out of Marcelo Bielsa’s side.

The former Wolves man has failed to make the United matchday squad for their four Premier League fixtures this season.

His only involvement came in the EFL Cup defeat to Hull City when Leeds fielded a weakened team made up of fringe and young players.

Douglas has slipped to fourth in the Leeds left-back pecking order, which is led by Stuart Dallas.

Ezgjan Alioski has been Bielsa’s preferred understudy for his versatile teammate, who is also a converted winger.

Youngster Leif Davis has also been preferred to Douglas and made the bench for recent Leeds matches.

The Scotland international was expected to make a big impact at Elland Road when he joined from Molineux for £3million in the summer of 2018 after his key role in their promotion campaign.

But he has had a stop-start United career that has seen him accumulate just 44 appearances in all competitions in three seasons.
