Well they started off the season quite strongly with their new signings Cissoko and Lisandro fitting in almost immediately, Pjanic was played in his preferred attacking midfield position(as opposed to the first season where he was played as a winger), also Bastos was turning in some strong performances on the right wing. Then around November they started having a hard time, and suffered a big loss to Nice where they were completely outplayed and ended up losing the game 4-1, and all their former players Remy, Hellebuyck and Mounier all having great games. Then they had that amazing 5-5 draw with Marseille

, anyway they were really poor until the much needed winter break. After the winter break they were again back to their winning ways, but reaching the semi's of the CL kind of had a bad effect on their league form, so at the end of the season they started losing points everywhere, that eventually lost them the league to Marseille.
Loris was a fantastic throughout the season for them, he was the Ligue's best keeper last season imo, he did very well.
Cris was quite inconsistent and rather mistake prone last season. It didn't help Lyon that Boumsong was injured for large chunks of last season while Mensah was out on loan to Sunderland.
At first they played Bodmer as centerback but he turned out to be a disaster there, so they eventually put Toulalan back there, he did relatively well and was actually better in CB than Cris was. I'd say Cris poor form affected Lyon as he has always been a dependable defender for them.
Revelliere was his usual consistenly just above average self, Cissokho on the other side was quite good, other than a few horror games here and there, he had a good season all in all, he was very instrumental in the CL too.
In midfield, Puel rotated and never really had a stable selection there. When Toulalan was played as CB, which happened a lot last season, sometimes Gonalons filled in as DM sometimes Makoun did, the latter was very inconsistent and you could never know what to expect of him. Gonalons on the other hand, impressed whenever given the chance, and showed maturity above his age, he had a good season last year.
Kallstrom was another one that was inconsistent last season, not a very strong player mentally imo. When the team was playing well he was always very good, but when the chips are down, you can always rely on him choking it out. At times he was magical though last season. Pjanic was their best midfielder though, he had a brilliant season last year, i think he was their top assistman, plus he was the midfielder that scored the most goals. He was very instrumental for Lyon last year.
Upfront, Lyon started the season with Gomis in the center, while Lisandro was on the left and Bastos was on the right. Gomis was wasteful and poor most of the time, so eventually Lisandro was put in the center, the right became a rotation between Bastos and Govou and the left was for Cesar Delgado.
Delgado was very good in the second half of last season, he was good in the big games particularly and he made that left hand side his. Lisandro was arguably Lyon's best player closely followed by Pjanic, but i'd give the edge to Lisandro, wherever he was played he was a constant nuisance to defenses, and he always worked extremely hard for his team, all in all he was quite consistent too.
As for the right hand side, it remains forever a mystery how it could be a rotation between the extremely mediocre Govou and Bastos who was most of the time quite decent. Bastos always played better, plus he chipped in with goals, mostly from long range, so he added a different dimension to Lyon's attack, but despite that Puel kept it as a rotation between him and between Govou who offered virtually nothing to be honest.
Sorry for making it too long, but i'm bored and have a lot of time on my hands. Cronios who?
