Marco Silva has made some great progress in the transfer market so far this summer with the signings of Richarlison and Lucas Digne already secured, and a recent report from Spanish media outlet Sport suggests another exciting acquisition is on the way with Yerry Mina in line for a switch to Goodison Park.

Following a thoroughly impressive World Cup campaign for the Colombia international which signalled the beginning of weeks of speculation which have linked him with a transfer to Manchester United, Everton supporters should be delighted to hear their club are on the brink of signing Mina.

However, it seems that Marco Silva is eager to add further quality to his defensive unit as TEAMtalk claim he wants to sign a player with proven Premier League experience, namely Marcos Rojo.

But the same report claim that Everton are not totally hell-bent on signing Rojo and would consider taking either Victor Lindelof or Chris Smalling if they cannot agree a deal for their first-choice target.

The fact Everton are targeting the acquisition of two new centre-backs certainly makes for positive reading for supporters who will be hoping their club can challenge the established top-six sides for a place in Europe next season.

The arrival of Mina, Rojo or even Lindelof would certainly represent a positive step in the right direction for the club, but a deal which saw Smalling arrive at Goodison would lack the progressive thinking which they need to instigate genuine improvement next season.

Smalling has plenty of experience playing for a Champions League standard club with huge expectations, but that fact alone does not justify Everton's interest.

At 28-years-of-age Smalling has never quite shown the conviction you would expect of a player whom regularly starts for Manchester United, and it's become increasingly apparent that he's nothing more than an average Premier League standard defender during his 8-year stint in Manchester.

With that in mind, Everton should turn their attention towards a player whom will genuinely enable the club to take a huge step forward in their development under Marco Silva.

Everton have been stuck in a frustrating position in the Premier League in recent years in which they have fallen well short of the standard needed to breach the top-6, and signing Smalling would simply serve to reinforce their position as a club who are so close, yet so far away from breaking the mould.

Smalling would certainly not be a bad signing for Everton to complete, but if the club have genuine ambitions of instigating significant change in the top-flight, they should turn their attention towards targets of genuine high quality.
