I just drop players if they do not deliver after some matches unless I do not have a decent player as alternative, but then I will be in the market to look for one and maybe even a replacement. I dropped my fast training DC with Aerial Defender special ability this season, and I even prefered playing a lower quality but better performing DC that provide solidity at times in the past. The same was done to the GK I bought from the daily recommended list. The DC of course still has a future in the team if he improves later. I also sold another DC, same fast trainer with same special ability this season for the same reasons. He was bought last season, was a first team player, but I rarely felt his presence (except in 1-2 matches) and he was finally sold to make place for other players after being judged by me to be the worst central defender in the team performance-wise. I like players that perform well and are consistent. Form is something but there are players that may get a 9 once a while but in most matches, they get 6 or 7s. Those players are undesirable. Better have players that will give an 8 in every match or so.
