As title said, is there any downsides for the tutor while tutoring?

Personality clash is the only downside I can think of. I tried to tutor a right back with a first team right back, who has a Resolute personality, but the "student" was ambitious and they ended up hating each other, which stoped after a month or two. Apart from that, I dont think theres anymore. They may also pick up bad habits from the person tutoring them, for example, arguing with ref, more bookings etc.
