Everton have been given odds of 2/1 to sign the Netherlands international, while Middlesbrough are rated at 3/1 to recruit the 28-year-old goalkeeper and Crystal Palace are rated at 6/1.
The odds of Everton, Middlesbrough and Palace should not come as a surprise, as the three Premier League clubs have been linked with Krul.
The odds of West Ham signing Krul are evens (1/1), and this does come as a surprise. Adrian is the first-choice goalkeeper for the London outfit, while Darren Randolph is his back-up.
Krul was Newcastle’s first-choice goalkeeper before he suffered a long-term injury last season.
It is hard to see the Dutchman join West Ham this summer if he is not guaranteed regular first-team football, which he would not get as long as Adrian is part of Slaven Bilic’s team.
