Yaya said after one of the games last season that Liverpool were the toughest opponents he has faced after coming to England. Although our season went badly overall, I personally was delighted to here that from Yaya, and this season I can bet that we will make it even more tougher than earlier.
But realistically I see City to be the favorites for this tie if it's not heading for a draw. The Yaya factor has gone up a couple of notches this season and add to that the good form Dzeko, Silva( as always), Nasri and a couple of others are showing, it is going to be tough for any team on any day and also there is a chance that Aguero could return as well.
As for us we rely on the fast paced attack and link-up play of Suarez-Sturridge-Coutinho/Sterling but we have to really be dominant in mid-field for this one as getting enough space will not be easy for us, but if we click like in the previous big matches at anfield and click early then I guess we will have the edge.
But the deciding factor to me I guess would be the key to unlocking a weak defense which can be attributed to both the teams.
