To be fair, all the players you mention have played recently. I didn't see all the friendlies so I haven't seen Toko play. SH hasn't brought him on once since the season started.
This was in the Argus today.
Holla brings much-needed experience to Hyypia's midfield options. His arrival could, depending how he is used, have implications for Toko - signed before Hyypia was appointed - Ince and for the future at the club of fellow Dutchman Agustien.
