Celtic have agreed to pay Motherwell a lower fee for David Turnbull than last year, Football Insider can reveal.

This site broke the news earlier today that the Scotland Under-21 midfielder is undergoing a Parkhead medical as he puts the finishing touches to his transfer.

A Celtic source has told Football Insider that Motherwell have accepted a bid of an initial £2.75million plus two separate tranches of add-ons each worth £250,000.

The total cost of the deal could rise to £3.25m, which is marginally lower than the costs agreed before Turnbull’s 2019 transfer collapsed at the eleventh hour.

Fourteen months ago, Celtic were all set to pay £3m plus £500,000 of add-ons for the young playmaker.

The deal now hinges on the outcome of scans on Turnbull’s knee after he underwent surgery this time last year.

Should the medics give the green light, Celtic are set to announce the signing in the next 24 hours.

It will bring to an end a lengthy pursuit for the Scottish champions, who are simultaneously looking to finalise the sale of Tom Rogic.

Neil Lennon and his staff have been keeping a close eye on Turnbull in the early-season matches and been convinced he is fully recovered from the knee surgery that ruined his 2019-20 campaign.

Turnbull blossomed in 2018-19, scoring 16 goals and supplying seven assists for Motherwell from just 34 matches in all competitions.

He has started all five of their SPL matches this season, scoring in the 2-2 draw against Hibernian.
