Depends. If you play with attacking fullbacks like I do then yes. The mid is not worth the money but like the above poster says If ya an english club then spending high amounts of money on transfers should not be a problem.
The most I've paid for was Renato Sanches for 30M ( and 50% selling fee cause i have no intention to sale).
The rest were mostly free or transfer listed.
I have lots of money, i'm the 4th or 6th richest club in the world.
