Melbourne City captain Patrick Kisnorbo has claimed he has no idea who will replace injured defender Connor Chapman in the Melbourne Derby.
Chapman tore the medial collateral ligament in his left knee during the first half of City's 4-0 win over Newcastle Jets last week, and he is set to miss up to three months with the injury.
The 21-year-old has been the only constant in City's back four this season and Kisnorbo - Chapman's central defensive partner in the past two matches - has conceded the youngster's injury is "a big blow" to John van 't Schip's team.
Many expect ex-Fulham defender Aaron Hughes to replace Chapman on Saturday night against Melbourne Victory.
Hughes is working his way back to fitness after a calf injury. Kisnorbo, however, gave away nothing on Wednesday.
"At the end of the day, I don't pick the team. The coach is the one that decides that," City's skipper told reporters.
But Kisnorbo clearly rates Hughes highly.
"He's a great pro. You always see him in the gym working," the ex-Socceroos defender said.
"He's a model professional and he's someone that the younger boys look up to because they see him do his work. So he's great to have around."
City head into the derby at AAMI Park full of confidence they can turn the tables on their archrivals having suffered a 3-2 loss back in Round 2.
Kisnorbo and Co. have won three straight games, scoring 14 goals in that time, while Victory are scoreless in two consecutive matches - 2-0 losses to Wellington Phoenix and Western Sydney Wanderers, respectively.
"Yeah, three wins in a row. We've scored a lot of goals. We have got a bit of momentum but, you know, football changes very quickly," Kisnorbo said.
Victory will have a chance to bounce back pre-derby away to Perth Glory tonight (Wed).
