As others have suggested, moving the MC to another spot may be the best idea, and I see Tanase is left-footed, but you have him on the right side of the field. Switching him with Lazareanu may yield better results, especially if Lazareanu is right-footed.

Also, GK performances are weird. I had one that was slowly getting lower and lower ratings, and he was letting in more goals to actually support it. I bought a higher rated GK to replace him, and now use the original GK for friendlies and less important matches. His form is now much better and he appears to be playing better as well.
