The Red Devils are now said to have offered £45m including add-ons for the centre-back after initially depositing £37m for the 24-year-old. Martinez is believed to favor a move to Old Trafford due to his relationship with former manager Erik ten Haag. Arsenal, meanwhile, have offered up to £40m in add-ons and although no official response has been received, there is a growing belief that United are now the first choice for the defender. The player wants a move to the Premier League and wants the Amsterdam giants to accept United’s offer as he targets a reunion at Old Trafford.
