Tadic scoring for Saints against Aston Villa
Everton have 'kept tabs' on Southampton winger Dusan Tadic, according to the Sun (Tuesday edition, page 49).
The Saints are set to open talks with the Serbian over a new contract at St. Mary's amid interest from Bundesliga side Schalke 04, who see him as a potential replacement for Leroy Sane, the report claims.
But Everton are also said to have monitored the situation, with new boss Ronald Koeman the man who brought Tadic to English football from FC Twente two years ago.

The Dutchman, who's already recruited former Southampton loanee Maarten Stekelenburg at Goodison Park this summer, has also been linked with moves for Saints pair Fraser Forster and Virgil van Dijk (Daily Record), as well as Graziano Pelle (Star) and Victor Wanyama (Record) before their moves to China and Tottenham Hotspur, respectively.

Tadic, 27, has two years left on his deal at St. Mary's, but the South Coast club are said to have lined up Brighton & Hove Albion's £7.5 million-rated winger Solly March should the worst happen.
The 21-year-old recently turned down the Seagulls' offer of a new contract.
