The Red Devils signed three players in the summer transfer window after having wrapped up deals for Aaron Wan-Bissaka, Harry Maguire and Daniel James.
Manchester United are bound to start being linked with a host of other players in the coming weeks and months as the January transfer window draws nearer.
The summer window was Solskjaer’s first opportunity to strengthen his squad after his appointment as Jose Mourinho’s successor at Old Trafford.
And former Manchester United defender Neville feels that Solskjaer will need to get a number of transfer windows under his belt before his team can be truly assessed.
Neville also believes that Manchester United should be targeting a title challenge in around two years’ time.
Speaking to Sky Sports, Neville said: “The most important thing about the transfer window for United and Ole Gunnar Solskjaer is that they don’t make mistakes, not that they do loads of business, but it’s about making sure they have the right type of players.
“It may seem like too far into the distance but I would suggest four or five transfer windows to get things absolutely right and get back to the type of squad he would want to challenge these Liverpool and Man City teams.
“I’ve said before, he’s got to be ready, not at the end of this season, not next season, but the one after, to challenge for the Premier League title.
“Potentially when Pep Guardiola has left Man City, or Liverpool have had another round of recruitment and another set of players in…Ole has got to be ready to pounce. It’s a long term thing, there’s not going to be quick fix or magic wand from any manager.
“United have tried David Moyes, they’ve tried Louis van Gaal, they’ve tried Jose Mourinho, all proven and Ole Gunnar Solskjaer is going down the long road, not the quick path.
“There’s no shortcut, there never is, and for me, it’s now about making it through these difficult moments, like losing to Crystal Palace and you feel like the world is going to fall in that but people must remain patient.
“I want to see the nonsense go, the speculation that players want to go, I want to see the disciplinary issues or the little tit-for-tat stuff over the last two or three years where there have been fall-outs, I want to see that go and the leaks. I want to see a team building slowly.”
Manchester United suffered a surprise 2-1 defeat by Crystal Palace in front of their home fans in the Premier League on Saturday afternoon.
They will attempt to get back to winning ways in the top flight when they take on Southampton away from home this weekend.
