One area of Everton's squad Marco Silva is looking to improve is at left-back. Sky Sports have recently reported that the Toffees have targeted Bayer Leverkusen's Wendell and Germany international Marvin Plattenhardt. But according to the Daily Mirror, the Merseyside club could now turn their attention towards Celtic prodigy Kieran Tierney in a move that must absolutely be pursued.  

The Breakdown

At 33, Everton's current first-choice left-back Leighton Baines is coming towards the end of his Goodison Park career and possibly his time in the Premier League. TEAMtalk reports that the England international could be set to join former team-mate Wayne Rooney in the MLS.

Baines is at the age where he won't be able to play 38 games a season or have the influence he once did on the left flank from a very physically demanding position and role. But he'd still be a useful asset to have and selling him would see Everton needing to sign two new left-backs during this transfer window.

Nevertheless, regardless of Baines' situation, Everton need a left-back for both now and in the future.

In that regard, £4.5m-rated (via Transfermarkt) Tierney is the ideal candidate. At 21 years of age, Tierney is still in the very early days of his career, yet already has a tonne of experience under his belt having cemented the position of first-choice left-back at Celtic.

As well as making appearances in the Champions League, Tierney has also played for the Scotland national team, further indicating the sort of footballing maturity he possesses despite being so young.

With all of that in mind, Tierney is a player that Celtic aren't going to let go without putting up a fight. Any potential transfer is going to be an expensive one, while Everton would likely face competition for the Scotland international's services, with the Times having recently reported on interest from Manchester United.

Everton, though, must put themselves at the front of the queue if there's even a remote chance of signing Tierney this summer
