For me it was a sign given by the game to change my starting GK.

I can't explain it otherwise how could a GK who is solid for 4 seasons in a row is suddenly not motivated and performs poorly.

It's not 5 games, it's nearly 20 now that my other GK is almost constantly in good form. I'm using the same formation, same instructions, same players, same everything. That's why a season nearly going south early on, eventually turned to a pretty good one. I'm 8 points ahead in the most requiring league I've ever had and I'm almost through to the semi-final of the CL after a 3-5 away victory.

That's my take whatsoever.
