Newcastle had qualified for the Champions League the previous season. So they had ample opportunity to strengthen the squad by adding star players to their squad. Because star players will not only come to Newcastle to play in the Premier League, they will definitely want to perform in the Champions League. It is more honorable. But the Newcastle management did not try to bring any star players into the team. And their performance this season has been poor. Qualifying for the Champions League is almost impossible for them now. Now I don't think coach Eddie Howe will be able to add any first class star players to his squad.
Yes, You are right, it is clear that Newcastle united has not been able to take advantage of opportunities this season. Where they participated in the champions league this season but Howe did not make any outstanding signing in the previous transfer window. So it is quite natural that this season they experienced quite a significant setback in their game. Even Newcastle united were knocked out quite early in the Champions League and were not even able to compete strongly with AC milan to win 3rd place and in fact newcastle united was really not strong in the Champions league.
In this way, the Newcastle united players seemed to be under quite a big burden after being eliminated from the Champions League, Where they were no longer consistent in the Premier League, which made them suffer consecutive defeat. Newcastle united also lost to Liverpool with a score of 4-2, which indicated that Newcastle united was no longer a strong enough team like the previous season. Of course, the bad results in the last few matches have certainly made them even further behind the teams ranked in the top 4.
