Not sure why, but I'm always so against going for those negative points. I wanna change 8 players but would never go -16 to do it, although 16 points across 5 GW's actually does make sense across 4 defenders.
Currently with 4 transfers I remain with 4+ mil in the budget, with a shitty defence and no chance of points.
There are managers that take hits like crazy and those that will never take hits I am pragmatic. I look at the team at any given time and make a mental calculation. If I believe that following equation stands I go for the transfers, otherwise I don't. Simple as that
new players points - negative points > old players points
Time frame is 3-5 weeks, depending on players, fixture swings and stuff like that. If player is someone like Saka or Palmer it can even be much more.
The problem is that in 5 GW's I'll want City/Liverpool assets back, and then my fancy defence is a problem again.
That is a problem and if you are just gonna circle back than of course don't do it.
