First things first, Everton should attempt to keep Romelu Lukaku at Goodison Park.
If they can't secure his permanent services, then they should opt for another loan deal. He's one of the best up and coming strikers in world football and would continue to progress under Roberto Martinez.
Martinez should also look to bring Jack Rodwell back to the club in the next window. The youngster's career has hit a standstill at Manchester City and he could light up Goodison Park once again.
