Of course, the example of PSG showed that for success in football it is not enough to have rich owners and that it is also necessary to have a good development plan and strategy.
If you remember, when the new owners took over Newcastle 2 seasons ago, the club was on the brink of relegation. In just one year, they saved themselves from relegation and entered the Champions League, which is a great success.
This tells me that the new owners of Newcastle know what they are doing and that Newcastle could be a very serious competitor to Manchester City in the future. They have the finances to succeed, they seem to have a good plan and the patience, time and knowledge to implement it.
The time will show.
Yes, if Newcastle also being trained by a coach who has competence and good scouts to bring in quality players, then they can become City's competitors for the EPL title. However, every clubs still needs a process to get to the UCL final. without a coach who knows the UCL and can bring in the right players, Newcastle may find themselves in a tailspin that has already happened
Newcastle United already achieve their best results in this season with no one was expecting they could be in top four even their coach is not world-class but till he is doing much better, and they also have no enough quality players but as they are doing most chances in coming years we can expect good results from them with things could be improved, and they will be also had more quality players in coming years right now their approach is positive because they are not spending huge funds for the big players which are never been ideal to won the trophies with many already know how failure is PSG after spending huge funds but no chance in Champions League, but Newcastle United can go through for the better future as they will also need to have good winning unit which helps them for bringing better results without any funding.
