YAKUBU is hoping to hand David Moyes a derby day selection headache after returning to full training.
The Nigerian striker was put through his paces at Finch Farm yesterday alongside team-mate Joseph Yobo, following their safe return from the African Cup of Nations.
Both players have been on international duty with Nigeria throughout January, but are desperate to prove they are fit enough to figure in the squad for tomorrow's Anfield showdown.
Their return has come as a timely boost for manager Moyes, who saw Louis Saha limp off against Wigan Athletic last Saturday, and was also missing centre-half Sylvain Distin at the DW Stadium.
The Super Eagles missed out on a place in the final in Angola but finished third in the tournament after beating Algeria 1-0 in the third-place match.
Neither of the Everton pair featured in that match, both remaining on the bench.
Yobo limped out of the Group C match with Mozambique early on in the competition and did not play again for his country due to a hamstring strain.
Moyes will give both men the chance to prove they are full fit, as he also waits on fitness updates on Mikel Arteta and Jack Rodwell. Meanwhile, Everton's skipper Phil Neville insists his side must finally overcome their 11-year wait to beat Liverpool at Anfield.
