Former Tottenham and Barcelona boss Terry Venables reckons Edin Dzeko could be a derby gamebreaker today.
Manchester City striker Dzeko is expected to start from the bench at Manchester United.
Venables told The Sun: "With Rio Ferdinand out, you have to say United's defence is not as strong as it could be.
"City, and Tevez in particular, will surely be looking to exploit his absence.
"I suspect Mancini will go with a 4-5-1 or 4-4-1-1 formation, with Silva linking up with Tevez.
"Yet, at some stage, I would like to see them maybe go a bit more adventurous and bring on recent £27million signing Edin Dzeko.
"I feel the Bosnian could cause United some problems with his aerial ability. The stats show United have conceded the highest percentage of headed goals in the top flight - 33 per cent."
