Manchester City Star David Silva in Doubt for Manchester Derby

Manchester City's chances of leapfrogging crosstown rivals Manchester United in the English Premier League have taken a massive blow after it was revealed Spanish attacking midfielder David Silva may not feature in the clash. Silva is reportedly carrying a hamstring injury and isn't likely to recover on time to face the Red Devils when City welcome them to Eastlands.

In an interview published on Goal.com, City manager Roberto Mancini confronted press ahead of their dead-rubber tie with Borussia Dortmund in the Champions League. When asked about the absence of a few key players—including David Silva—from the UCL matchday six squad, Mancini said:

"

[David] Silva is not here because he has a hamstring injury, and we do not know at the moment if he can recover in time for the derby.

We will try, but we will have to see.

"

Following their elimination from Europe's premier competition, City have turned all attention to domestic duties. Following a 1-1 draw against Everton in their last outing, Mancini's side have fallen three points behind Manchester United at the top of the table.

Despite this, a win on the weekend would see City jump ahead of United in the title race on goal difference. The defending English champions remain the only unbeaten side in England's top-flight; however, six draws from 15 matches has The Citizens sitting in second place.

This season, Silva has appeared 12 times for City in domestic league action. The Spanish International has netted once and bagged two assists in the process. With James Milner, Aleksandar Kolarov and Gael Clichy also in doubt for the United clash, Mancini's men will certainly have their work cut out for them.

Manchester City welcome Manchester United to the City of Manchester Stadium on Sunday.
