Everton are in talks with the Málaga striker Sandro Ramírez and the Ajax captain, Davy Klaassen, as the club look to make their first additions of the summer to Ronald Koeman’s squad.

Sandro, the Spain under-21 international, was spotted in Liverpool on Sunday and could agree a move to Goodison Park this week. The former Barcelona forward has a €6m buy-out clause in his Málaga contract and had also been heavily linked with Atlético Madrid only for their transfer ban to enhance Everton’s prospects of a deal.

Sandro scored 16 goals in 31 games for Málaga last season and Koeman needs to increase his striking options for next season with Romelu Lukaku coveted by Chelsea and having released Arouna Koné.

The Everton manager also wants the Ajax playmaker Klaassen to improve his side’s productivity in the final third. The Europa League finalists, who lost their coach Peter Bosz to Borussia Dortmund last week, are seeking around £25m for the Holland international and are understood to have received an approach from Everton as well as other European clubs.

Klaassen is open to a move to the Premier League and is well known to Koeman, who scouted his compatriot several times last season. The arrival of the Holland international at Goodison would inevitably cast further doubt on Ross Barkley’s playing prospects at Everton next season, with the England international stalling over a contract extension, although Koeman has stated he wants more creative options regardless of whether Barkley stays or goes.
