Rafael Benitez says he has no long-term plans for Newcastle United as he reiterated his disappointment in the club's transfer dealings.
Following their promotion from the Championship, Newcastle have started their Premier League return with two defeats.
Although Jacob Murphy, Florian Lejeune, Joselu and Javier Manquillo have all been brought in this summer, Benitez expected more investment in the first team from owner Mike Ashley.
"We won the Championship and we made £30 million profit. I had a meeting with Mike and I was expecting we could be in a better position than we are now. We are not," he said.
“We will see if we can improve as much as we can this week. I will try to do my job.
“How much can I improve the team? It depends on how well we work and how much the players can learn.
“My aim is trying to improve things, so when I leave, whenever it is, I would like to be sure that the team and the football club will be better.
“Normally, managers talk about projects saying they need four or five years. I’m not talking about that, because you never know in football.
“But when we came here we knew there were some issues and we had to improve things. I am sure we have improved some things. But we need to improve more."
The Spaniard does, however, wish to take the Magpies to a stable position in the Premier League, but insists it will take time.
“What I want is that we have a football vision and allow the business to also be productive and make a profit, but football has to be a priority.
“In Europe it is more difficult to do that. [Newcastle] is a club that has potential and we will try to reach that.”
