I'm guessing that as you haven't been playing long then you don't have much money to buy players.
That's just life, so welcome to the game!
I haven't been playing long either and I have exactly the same problem so I do understand where you're coming from. All my money goes on construction costs and I haven't anything left to buy any decent players.
That's fair enough as I'm starting at the bottom and have to build the club up from nothing. So I have spent my few seasons investing in the infrastructure and stadium so that I will have a transfer budget in the future. When I can buy a few decent players and even train my own, then it will have been worth all the effort.
Nothing comes for free.
Note. You can always get a few decent loan players, which are essentially free for the season.
