Possibly but unlikely in my view. I think we could have started to solve the issue by getting a better quality midfielder but we wouldn't necessarily have solved the issue immediately with one signing because our problems are deeper/wider than one midfield position.
We have a team that has aged together, just come out of a long season that ended flat, players with the World Cup on their minds and players all over the pitch performing below par.
We also have a stubborn manager who always tries to find solutions from within the squad first and perhaps doesn't immediately accept what sometimes seems obvious to everyone else.
Then there's FSGs own FFP policy.
I don't believe that the whole team has suddenly aged, the problem is mainly the midfield. We have signed 3 younger forwards, Jota, Diaz and Nunez, at the back we signed Konate and Tsimikas, with both TAA and Gomez young. I don't understand why some people are saying we need to change the whole team, if we had signed a good midfielder, we wouldn't be in the current crisis
