Manchester United boss Ole Gunnar Solskjaer admits Victor Lindelof isn't a certainty for Sunday's derby with Manchester City.

The Swede was an unused substitute against Crystal Palace for the 0-0 draw as he manages a recurring back issue.

While Solskjaer was tight-lipped in his post-match press conference about who might partner skipper Harry Maguire against City, he was hopeful Lindelof would be among his options.

"Victor struggled with his back, you know when he plays on a Sunday night, that was a demanding game, he did really well and I didn't want to play him if I didn't have to and Eric is more than capable and he's played really and he's played really well tonight as well," he said.

“So [I'll make a] decision on Sunday, I'm not giving [it] you now. Hopefully Victor's back is OK, [now] that he's had that rest that he needs."
