English Premier League club Everton have agreed a club record fee of $22.31 million with Middlesbrough for Nigeria striker Yakubu Aiyegbeni.

After an unsettled pre-season the striker had been linked with a return to Pompey after 'Boro signed strikers Tuncay Sanli, Ahmed Mido and Jeremie Aliadiere.
Despite Middlesbrough manager Gareth Southgate previously saying the striker was not for sale, a deal looked likely after he it was revealed a few days a go that the player was no longer training with the squad.
Everton, which opened the Premier League season with two wins and a loss, have been seeking an experienced striker to partner England forward Andrew Johnson after selling James Beattie to Sheffield United.
