Real Madrid are poised to sign the most lucrative kit sponsorship contract in club football after agreeing a deal with Adidas that will see them eclipse Manchester United's record-breaking venture with the German manufacturer.

According to Jose Felix Diaz of Spanish daily Marca, Real could rake in as much as €140 million (£106 million) per year "if all clauses are met" in their new contract, which is understood to be a 10-year agreement.

That means Los Merengues stand to receive an eye-watering €1.4 billion (£1.07 billion) over the course of the decade-long deal, a massive 40 percent more than the £750 million deal United signed last year.

Adidas now boasts a collection of the world's biggest shirt deals, with Bayern Munich's reported by Diaz as potentially the biggest over the duration of their 15-year contract, worth "just over €60 million (£46 million)" per season. However, Diaz added that number is understood to rise to €90 million (£69 million) toward the end of the deal.

The Mirror's Ed Malyon went one step further and detailed that Real's rumoured €140 million-per-year agreement is more than Chelsea, Arsenal, Liverpool and Barcelona make from their kit deals combined.

If Manchester United's very active stance in the transfer market since signing the new deal is in any way linked to the deal they signed with Adidas last year, Real Madrid fans may look forward to their club also investing more heavily.

After signing Gareth Bale for €85 million in 2013, followed by James Rodriguez's €80 million arrival in 2014, last summer was a slightly slower transfer window for Los Blancos.

Manager Zinedine Zidane is attempting to re-establish Real Madrid as a major force both domestically and in Europe, and this record-breaking contract could help assert their presence as a powerhouse once again.

Diaz reported the deal will be signed before the end of this season.
