Schalke boss not only one worried

Schalke always have three managers, their supporters will tell you: the last one, the present one and the next one.

For Roberto Di Matteo, already under scrutiny seven weeks into his new job, that sense of insecurity is probably a familiar feeling, but he is not alone.

The fifth round of Champions League matches this week will be a tense time for more established managers as well, even this early in the season.
