Newcastle United have agreed a £19.6million deal with Ajax for Sean Steur.

The fee will rise to £22.6m with add-ons for the 18-year-old midfielder who is set to join on a five-year deal.

The Netherlands Under-19 international has made 25 appearances for Ajax and is regarded as a top talent.

However, Ajax need funds to strengthen their squad and also have young Belgian midfielder Jorthy Mokio who can play in the same role.

They have also asked for a 12.5 per cent sell-on clause.

As Daily Mail Sport revealed last week, Newcastle are continuing to work on a move for Freiburg’s £40m-rated Johan Manzambi, and are considered frontrunners for the Switzerland international midfielder despite interest building from other clubs.

Newcastle have already seen Sandro Tonali depart for Tottenham in a deal that could be worth up to £100million while Arsenal maintain interest in Bruno Guimaraes.
