Everton manager Marco Silva is on the lookout for a central defender to add to the summer signings of Lucas Digne and Richarlison.

However, the Portuguese coach has had no such luck yet with a move for his primary target for the position hanging in the balance.

The Breakdown

Goal reports Barcelona's Yerry Mina, who Silva had hoped would be the man to improve his central defence, is now unlikely to move to Goodison Park.

As a result, the Toffees have turned their attention towards Manchester United's Marcos Rojo, who could be pushed down the pecking order at Old Trafford with the Red Devils looking to sign a new centre-halve themselves.

£16.2m-rated (via Transfermarkt) Rojo, compared to the likes of the declining Ashley Williams and ageing Phil Jagielka, would probably be a welcome upgrade to supporters at Everton.

How much of an upgrade, however, remains to be seen.

Rojo has been in the Premier League since 2014, but there are still many question marks surrounding his ability as a defender.

The 28-year-old's tackling and overall aggressiveness, in particular, has often made him a liability at Manchester United.

Rojo, at times, looks like a ticking time bomb waiting to go off, although -- largely due to incompetent refereeing -- the Argentina international has managed to avoid being sent off in the Premier League.

Should Everton sign Rojo and the former Sporting Lisbon man be able to add some more discipline to his game under Silva, then the Toffees could be getting a good player.

But at 28, Rojo should not be looking as raw and rash as he sometimes does. Bearing that in mind, it would be in Silva's best interest to also consider other central defenders if a deal for Mina is really dead.
