GK – Djordje Petrovic
The Serbian is making the No.1 jersey his own with his recent performances between the posts.
Petrovic made two excellent saves to deny Harry Wilson and Raul Jimenez in the victory over Fulham last time out.
Fans will be hoping that the 24-year-old won’t be troubled too much against Boro.
The Blues will be looking to keep a clean sheet in order to give themselves the best possible chance of overturning the first-leg deficit.
