Watford are set to complete the signing of Newcastle United defender Daryl Janmaat.

The Hornets have agreed a fee in the region of £7.5m with the Championship club and the deal is expected to go through by tomorrow.

The Netherlands international right-back, who has 27 caps, is believed to be having his medical ahead of a move to Vicarage Road.

Janmaat joined Newcastle two years ago from Feyenoord and made 77 appearances for the Magpies. 

The defender, who will be comfortable slotting into the right wing-back role in Walter Mazzarri's preferred 3-5-2 formation, has played twice this season for Newcastle with his last appearance coming in the home defeat to Huddersfield Town.

Newcastle have agreed to Janmaat's sale with Rafa Benitez's side lining up Tottenham right-back DeAndre Yedlin as his replacement. 

Janmaat's arrival raises doubt over Brice Dja Djédjé's role at the club with the right-back still sidelined due to a foot injury sustained before signing from Marseille this summer.

Speaking about Watford's remaining activity before the transfer window shuts in a week, Mazzarri said: “The club knows the way I feel. There are probably one or two players that will come but I’m not making anyone leave.

"If some of the players want to leave, because they’re not getting enough playing time, then it’s up to them."
