Manchester City boss Sven Goran Eriksson admits their attack will now be based around new signing Benjani Mwaruwari.
"I think he will fit in very well, he's played by himself for Portsmouth many times, and I hope he can play on Sunday," Eriksson told City's official website.
"He's a very good footballer, he's scored 12 goals in the league so far this season which is a good record.
"When we had the opportunity to take him, I did not hesitate at all, my reaction was 'yes, let's take him'.
"He's 29, he has a lot of experience, he's very strong and is a proven goalscorer. We need that, that's for sure."
City have flourished operating with a five-man midfield this season, rising into contention for a European place, but have found goals from forward players in short supply.
Eriksson is hoping the former Auxerre player - whose tally this season represents only the second occasion he has reached double figures in eight league campaigns in Europe - is the missing link.
"He's always been a hard worker," Eriksson added. "I know people who worked with him at Grasshopper FC in Zurich a few years ago, they said he was a goalscorer and a hard worker even then and it's good if you can have that combination in a player.
"I don't know him well yet, but he looks very lively and is always looking around him to see what's going on. I'm sure he will be a very good signing for us."
City completed the protracted deal on Tuesday by paying half of the overall £7.75million fee - the remaining balance is due when the player has completed 25, 50 and 75 starts for his new club.
