Wise further angered Newcastle United fans when he was shown often attending Chelsea home games (and the FA Cup Final). Later, it was revealed he spent the vital last day of the 2009 season in Dubai celebrating his wife's birthday, showing a surprising disinterest in the outcome of a club in which he had very recently been inolved. In fact both of Wise's signings (Xisco and Ignacio Gonzalez) failed to feature in the club's final game. While these signings have received fairly negative views from Newcastle fans, the late Sir Bobby Robson and newspaper pundits have slated them as second rate signings.
On 1 April 2009, following the appointment of Alan Shearer as manager on an interim basis, Newcastle released a statement that Wise had left his role as Executive Director of Football with immediate effect. The club also confirmed that there were no plans to replace Wise.[49]
In an interview with the Guardian on 28 July 2009, it was revealed Wise is still receiving £20,000 per week from Newcastle United and was cited as one of the many reasons buyers were reluctant to purchase the club.
After the death of Sir Bobby Robson, The S**'s Bob Harris wrote how Robson told him: "My biggest disappointment was Dennis Wise, a director of football who was hardly seen at the ground, and who brought in players who were neither suitable, nor right, for Newcastle United. I forgive most people, but I am not sure I can forgive Wise for what he did to my club.
