The coach won't dip into the transfer market even though he feels his side would be top were it not for Samuel Eto'o, Fernando Torres and Demba Ba's failings in front of goal
The Blues sit third in the table, five points behind leaders Arsenal, with Samuel Eto'o, Fernando Torres and Demba Ba having netted only four league goals between them this term.
"If you tell me [Sergio] Aguero has scored already 10 or 12, [Alvaro] Negredo 10 or 12, [Edin] Dzeko four or five, [Wayne] Rooney eight or 10, [Olivier] Giroud eight or 10, [Daniel] Sturridge eight or 10, [Luis] Suarez 10 or 12 - if you ask me would I like my strikers to score eight, 10, 12 goals: Yes," Mourinho told reporters.
"If we had eight, 10, 12 [more] goals we would be top of the league. That's a reality but my strikers give everything and the team works hard."
Indeed, Mourinho claimed that there is little more that he can do to bring the best out of his misfiring forwards.
"What can you do more? We work, we keep working. That's the only way I know is to keep working," said the Portuguese.
"Of course we want the best possible results but I am not waiting for players, I am not asking for players.
"This is a period for the club and this is a period of my team where we have to try and improve the players we have and try to build a future.
"It is my squad. For good and for bad, it is my squad. Of course, it is not the perfect squad but it is my squad and I work with them until the last day.
"To criticise does not help me. What do I win by criticising my players? I win nothing."
