The Gunners are now sponsored by Adidas, having ended their association with Puma this summer.
A £50m deal was struck with the major manufacturers.
And that cash boost could ultimately help Arsenal solve their left-back dilemma.
Emery is still keen to bring in Scotland international star Tierney before next Thursday’s transfer deadline.
Nacho Monreal, 33, has just one year remaining on his contract and Sead Kolasinac has struggled to nail down the role, performing better as a wing-back.
Tierney, though, has shown at Celtic he is ready to take the next step in his career.
The 22-year-old has been pursued all summer by Arsenal, who have already had £15m and £25m bids knocked back.
The latest proposal did not satisfy the Hoops due to the payment structure put forward.
“Emery now hopes the £50m Adidas kit deal will ensure the Gunners complete a £25m move for Tierney”
However, according to The Sun, Emery now hopes the £50m Adidas kit deal will ensure the Gunners complete a £25m move for Tierney.
Celtic are not asking for more money in terms of the fee but would want a bigger percentage up front.
Arsenal have already been creative in the market with other players in order to cope with their £50m summer budget.
Midfielder Dani Ceballos was brought in on loan for a £3m fee, while William Saliba’s £27m arrival saw Arsenal pay little up front because of the centre-half’s loan back to Saint-Etienne.
Teenage forward Gabriel Martinelli – Arsenal’s first recruit of the window – cost £6m to sign from Ituano.
And their budget was slightly increased by the sales of David Ospina and Xavier Amaechi too.
The Adidas money could be the clincher in terms of landing Tierney, though.
The hope is he follows Nicolas Pepe to the Emirates Stadium within the next 10 days.
Arsenal are forking out a club-record £72m on the Lille forward, although only £20m is going to the French club now as a down payment.
The remaining £52m owed to Lille is said to be being spread out through payments over the next four years.
