Mansfield Town's pursuit of Liam Thompson, 24, has reportedly encountered a problem, and a potential deal is now on hold. It is understood that Mansfield had been hoping to complete a transfer for the English Derby County academy graduate, who is entering the final year of his contract. The delay is due to Thompson having travelled with the Derby squad to a pre-season camp in Austria. Derby County is currently not in a position to approve his departure as the club is short on numbers in the midfield department. However, Thompson's exit still cannot be ruled out, particularly as Derby are looking for midfielders. It is uncertain whether Mansfield are prepared to wait to sign the player; their campaign is scheduled to begin on August 8 with the first round of the Carabao Cup. According to Transfermarkt, the central midfielder's current market value is €1.50m.
