Everton recently confirmed the signing of Richarlison from Watford and, while another winger could still be brought in, manager Marco Silva will now be looking to strengthen other areas of his squad. 

That includes left-back and centre-back with the Toffees heavily linked with moves for Barcelona pair Lucas Digne and Yerry Mina (e.g. Sport).

However, Silva may also have his eyes on improving his centre-forward options.

Silva currently has Oumar Niasse and Dominic Calvert-Lewin to choose from when current first-choice striker Cenk Tosun is unavailable, and the Portuguese coach may feel that is not enough if Everton are to achieve their goals for the forthcoming season.

In the long run, the Toffees hope to eventually break into the Premier League elite and qualify for the Champions League. And if that is to become a reality, then more firepower is needed up front.

And the person to provide that is Juventus' Mario Mandzukic, whose future at the Allianz Stadium may be in doubt.

£18m-rated (via Transfermarkt) Mandzukic was already facing tough competition from the brilliant Douglas Costa for a spot in Max Allegri's starting XI, and the arrival of Cristiano Ronaldo will only make things more difficult for the Croatian.

Should that be the case and Mandzukic decides it is time to leave Turin, then Everton must lure him to Merseyside.

The Croatia international has been converted into a left winger by Allegri but, as he showed at the World Cup with his nation, he is still one of the most effective No.9s in the game right now.

Naturally, because of his change in position, at club level Mandzukic is not as prolific as he once was.

But the 32-year-old's hold-up play is still world-class while he remains a dominant figure in the air and a hard worker when his side are not in possession of the ball.

If used as a centre-forward again, Mandzukic easily has at least two more double figure seasons in him, which is something Everton could definitely do with in their pursuit of Champions League football.
