I just worry because it's not sustainable forever. We've done well with it so far because aside from Mahrez we've replaced the others. Southampton did well at first too (such as selling Lallana but bringing in Mane) but got to a point where they were just bringing in players who were worse/not as good as what they were selling. Lets not forget they were in a relegation battle the other year.
If you wanna keep selling then you've gotta keep bringing in good players, which we have done so far. I do accept it because it's natural. Bigger clubs buy our players just like bigger clubs by
