Middlesbrough supporters were aware that Hayden Hackney would quit the club following their Championship play-off final defeat to Hull City.

It was always a question of when and whether a team would be ready to pay the Teessiders’ asking price for their prized possession.

A number of Premier League clubs have expressed interest in the 24-year-old, but he has always preferred to join Everton, where he will be managed by David Moyes.

There have been contradictory rumours about how much the Toffees are paying for the central midfielder, but the full facts of the deal have now been revealed.

How much will Everton pay Middlesbrough for Hayden Hackney?

Hackney has climbed through the ranks at Borough to become their treasured asset, and he was crowned Championship Player of the Season following another outstanding season.

The 24-year-old had his greatest season in front of goal, scoring six and assisting eight times across all competitions, but he was unable to lead his club to the Premier League.

Of course, his lengthy injury spell came at a critical moment, and managerial changes hampered what had been a promising season for the Teessiders.

The finer terms of his move to Everton have now been revealed, with the Toffees ready to pay an initial cost of £16.5 million, plus an additional £5 million for appearances and £3 million for Champions League and England games, according to The Times.

It had been widely rumoured that Borough were holding out for £25 million, and while they may not get it all at once, they may get what they want in the end.

How should Borough use Hayden Hackney’s money?

Middlesbrough are already close to signing Kyle Joseph from Hull City for £5 million as they aim to improve their attacking line.

However, the logical thing for the Teesside club to do is replace Hackney, which will prove extremely tough.

Borough have been connected with a move for Leicester City midfielder Oliver Skipp, but the League One team wants £15 million, which appears to be an exorbitant sum for a player of his calibre.

The 25-year-old did show glimpses in the Premier League with Tottenham, but he has failed to live up to the promise at Leicester and must establish his talent.

Of course, Skipp has plenty of time to develop, but if he is recruited to replace Hackney, Borough fans will not be pleased.

While Middlesbrough has the remainder of the transfer window to find a replacement for their great player, they may have to pay an inflated fee because clubs will know they have the finances.
