According to journalist Duncan Wright on Twitter, sharing his report in The Sun, the lack of an option-to-buy in the Jesse Lingard loan deal risks being a 'big problem for West Ham', coming as he reported that the permanent price tag could skyrocket to £40m. 

Journalist drops worrying Lingard claim

Writing for The Sun, Wright explains that no option-to-buy could come back to haunt West Ham as they seek to secure Lingard on a permanent deal this summer.

His parent club Manchester United were apparently willing to offload him for around £20m when an agreement was reached for the loan deal. However, the Englishman's performances since then have made Old Trafford chiefs consider almost doubling his price tag, which comes as a 'big problem for West Ham' as this worrying claim emerges.

Transfer Tavern take

Having scored five goals and assisted two others already for the Hammers (per WhoScored), it's little wonder why Moyes wants to secure Lingard as a West Ham player, but the Red Devils' fresh stance poses real problems.

It is said that a new striker and permanent deal for the 28-year-old are Moyes' top transfer priorities for the summer of 2021, but if this claim comes to fruition, the Irons may be dealt a big blow in the hopes for the latter.

GSB and the club will be hoping that his price tag does not increase to £40m, as Wright has claimed it could.
