Newcastle is probably the most interesting club to look at these days because everyone is now waiting for their next move. It is difficult to tell whether they are going to pull off a 2nd Chelsea and invest over 500 million or whether they will gradually increase the quality of their squad and build something great over time. At least they have seen that the Chelsea project failed and that you can't just throw half a billion out the window and win the title. It needs much more than that. That's why I doubt that Neymar would really be that interesting to them. They know his history of injuries and his attitude.
Newcastle has been holding below 10th position for many years, and suddenly they qualified for the Champions League. I will only give them 2 more seasons to hold this feat before I will take them seriously. This might just be their lucky season.
