Watford have made a £4m bid for Hibernian left-back Josh Doig, according to reports in the Scottish media.

The Hornets are said to be confident that a deal can be reached with an offer of £2.5m upfront and the rest of the fee made up of performance-related add-ons.

Celtic, Arsenal and a whole host of other clubs, including AC Milan, Aston Villa, Leeds, Southampton, Stoke City and Cardiff City are said to be keeping tabs on Doig, but they may need to move fast to prevent his switch to Vicarage Road.

The Hoops could do with a player like Doig, who could provide competition for Greg Taylor, with Diego Laxalt returning to Italy at the end of his loan spell with the club.

However, with no new manager in place, it’s hard to see Celtic making serious offers for players until an appointment is confirmed. Hibs are thought to want a sell-on clause for Doig so that could still prevent his move to Watford from going ahead.
