Saliba's back for Arsenal - how does Arteta solve his defensive dilemma?

Arsenal boss Mikel Arteta will soon have a big defensive dilemma.

But it is one that will be both welcome to the Arsenal boss and the envy of other top teams across the continent.

That's because William Saliba - a key figure in the Gunners' title win last season - is back in training, having missed the entire campaign so far because of a back injury following his early withdrawal in France's World Cup semi-final loss to Spain.

The 25-year-old has been one of the Premier League's top defenders in recent seasons but - in his absence - summer signing Ezri Konsa has stepped in seamlessly to help Arsenal back to the top of the table.
