Why am i losing so much all of the sudden?

[Ted Theodore Logan]

this game is really starting to piss me off. i'm in my 8th season and my team's average quality is 53.5 so far i have won a great number of seasons and always do well in the champions and cup, i've won the champions only once but i always make it to at least the semis. but all of a sudden during the last few days of last season i started losing to every team i face (costing me last season's 1st place) i don't get it, i just can't win, so far i have yet to face a better team yet i can't beat them (teams with averages in the 30s and low 40s) its been about a week since i've won any matches. this new season in terms of average quality i'm the best team in the league (the guy behind me is a 49.3) but i'm at the bottom of the league with no wins...
i've always done a good job at keeping all my players at a similar level (meaning that my starters and subs are all pretty equal in quality) and i use all players throughout the season. ever since i started playing i use either a 3-5-2 or a 3-3-1-3 (mostly the latter) and these formations always seemed to work well against any team i faced (up until this losing streak i rarely lost a game. the games i would lose were normally cup or champions finals)
has this kind if losing streak happened to anyone else? i've never purchased tokens (but regularly download apps for free tokens), is this nordeus' way of telling me its time to start buying tokens? this is really starting to piss me off to the point where i'm about to just give up on the game and stop playing... anyone have any idea what could be the reason? thanks.
