He's underrated and overrated by loads of people, but I think Leighton Baines would be a good option to buy if Cole leaves. Everton could use some extra cash, we could use a free-kick specialist(?), and I've liked having some English blood in our back line. I don't want to lose that whenever Terry can't play. Failing that, we could always go for the best left-back in La Liga - Filipe Luis of Atletico Madrid. If he played for Barcelona or Real Madrid he'd be widely hailed as one of the best left-backs in world football, no doubt. Finally, the only other very good and realistic all-rounded left-back I can think of is Nacho Monreal. Obviously there will be loads of fantastic gems in all the 'smaller' leagues who I don't know exist, but from the top leagues, I'm sure any one of these players mentioned would do the job well here.
