New Everton manager Marco Silva is yet to make a single summer signing since taking charge of the club at the start of the month, has yet to be too active in the summer transfer window, which is perhaps no surprise given the size of the Merseyside outfit's squad.

The 40-year-old needs to sell before he buys before the window slams shut on August 9 as he looks to take the Toffees into European contention this term, and he will certainly be hoping that their business ramps up in the coming days and weeks.

The Portuguese boss, who has been urged by the fans not to sign a 26-year-old World Cup star with one labelling him as "awful",  will be working in tandem with director of football Marcel Brands to identify the targets that will help the club improve upon the eighth-place finish they achieved in 2017/18, following a disastrous beginning to the campaign that saw Ronald Koeman sacked in October.

While the former Hull City and Watford chief will have the stars he wants to bring to Goodison Park in mind, perhaps he should also be considering bringing some familiar faces back to Merseyside too, as there are ex-Blues out there that would make a big difference for them on the pitch now.

Here are three former Everton players Silva must look to re-sign this summer…

While the 24-year-old is currently starring for England at the 2018 World Cup having scored a brace in the 6-1 win against Panama on Sunday, the same can't be said of his 2017/18 campaign with Manchester City.

Injury and the arrival of Aymeric Laporte during the January transfer window restricted him to just 18 Premier League appearances, and his future at the Etihad Stadium could well be in doubt – especially if Pep Guardiola signs another centre-back this summer.

Meanwhile, Everton are in desperate need of a new centre-back themselves to partner Michael Keane, and the ball-playing Stones could be the perfect option for them if they are willing to pay the fee needed to bring him back to Goodison.

The Republic of Ireland centre-back only made 10 appearances in all competitions for Everton before joining Blackburn Rovers in 2014, and he has gone on to make a big impression for the Lancashire outfit and Brighton and Hove Albion since.

We mentioned previously that the Toffees need a new central defender this summer and while the 26-year-old Seagulls man may not be an attractive proposition in many ways, his performances for the south coast outfit last term suggest he could be a decent back-up for them.

According to WhoScored.com, the Irishman won 200 of the 294 aerial duels he faced in 37 Premier League outings, while he also made 71 blocks and 327 clearances.

Having only left Goodison Park for Chelsea in slightly controversial circumstances during the January transfer window, it would certainly be a turn up for the books if the 24-year-old returned to Merseyside this summer.

However, he has found first-team opportunities hard to come by at Stamford Bridge because of injury and being yet to find his form, which could mean that he is sent out on loan by the west London outfit.

A move back to Everton seems unlikely, but there is no doubt that he could add something for them in the final third, as he did on many occasions previously.
