I am losing with formation 4-1-2-1-2

Most of my player's quality are 7, no one are below 6. So do I still have to sell them and buy someone else?

Players averaging a "7" i'd keep. Any player averaging around a "6" i'd sell.

Its also important to note that some positions in general average a better average form than others.

MC's, DMC's and GK's usually have the poorest form in this game, so a player averaging between a "6" and "7" is recommended to keep until you find a few players at those respective positions that average above a "7".

ST's usually have the best form, so if you players form average is a "7" you have a dud. Generally, a quality ST is someone who gets mostly 8's with an occasional "7" or "9".

good defenders are usually a mixture of "7"s and "8"'s.

Reiterating the form thing, its bizarre but I have come across a one-star defender that got MOTM against me in the cup when I was level 6. This players quality was 16, so he was one-star for level 3 and I my strikers ranged from 5* to 7*. It was the only match I lost that entire cup tournament, which I went on to win. At lower levels its rarer to find low quality players dominating, but at higher levels where the quality gap is smaller (25 Q vs. 15Q is a larger percentage gap than 85Q and 75Q) so a players raw stats impact the match less, whereas hidden mode stats play a larger role in shaping player performance.

Opportunity and Expectation.

I'd reiterate pcmac's comments on form and player retention. Some roles are given more opportunity to do the rewarded things and others are given more opportunity to fail or just see the game pass them by. Those central midfielders (including dmcs)are just such an example and can be forgiven 6s if they are infrequent or in a winning set up. But if a dmc in an ND is not rating fairly often above 6 then either change the dmc or ND wasn't the best choice, imo.

I'd prefer it if the OP would post Squad stats.

I'd probably say that ratings also include an 'expectation' factor. If players are expected to fail in an action then they will be greatly rewarded when they succeed and punished relatively less when they fail. Just a theory.
