Gomes and Zouma are not available to buy apparently (well, according to the Echo anyway). Christensen may well be on his way out at Chelsea though, so he would be a target. If we cannot tempt Barca to sell Gomes / loan us again, then I would imagine Brands will have identified a target who is like for like and available.
I wouldn't be adverse to letting Walcott go either; remnant of the old regime sadly (though this is not his fault). Expensive and older. Lozano would be an ideal upgrade for the new, younger Everton.
Did you hear that huge thud then? That was the sound of my heart breaking
