Top of the league they may be, but Chelsea needcreativity and goals.
After one victory in seven, there is no need for panic yet, but listen to the words of Carlo Ancelotti and you realise he is in need of inspiration.
His time: Joe Cole could play an important role in the coming weeks
'We have lost a little bit of confidencein our play,' he said.
'It's normal when you don't get results. We have had some injuries. We are a little bit tired. This can happen.
'We did very well against Arsenal. Now we are a little bit down. Withoutthe African players we have to show we can play without them.
'But there are a lot of matches and it is impossible to stay all the time in the top condition. But today I think we gave signs that are good for the future.'
Shorn of their influential African influence for a month after today's derby against Fulham, the Italian has also suffered a further blow with Florent Malouda's suspensionfollowing two bookable offences at St Andrew's.
It places an extra burden on Cole, who is certain to start at Stamford Bridge this afternoon.
The 3,500 away contingent were howling for his involvement after an hour on Saturday.
And while this might have been the first time in 33 matches since late April that Chelsea have not found the net, this blank was coming.
You're off: Florent Malouda sees red
Against Portsmouth, West Ham and Birmingham, Ancelotti's side has scored once in open play.Although he has been used sparingly,it appears Cole's time has come.
'It's not easy for Joe to do his best after nine months out,' said Chelsea's boss.
'He has to improve and stay focused. He hasn't got to lose the confidence in himself.
'He has quality and he's a fantastic player. I think he will show this in his next game.'
Ancelotti was relatively pleased with Daniel Sturridge, but it is asking too much for him to shoulderthe goalscoring burden alone.
There would not be so much of an issue today had Chelsea not encountered a keeper in Joe Hart and a team in Birmingham who defend their goal as if their professionallives depend upon it.
Hart gave his most assured performancein the home goal by a distance. One save from Frank Lampard had the England star shaking his head in disbelief.He was also involved in a crunchingcollision with Salomon Kalou.
Sudden impact: Keeper Joe Hart feels the full force of Salomon Kalou's boot and is laid out
It brought back memories of Petr Cech's injury at Reading as Hart was down for seven minutes.
'The doctor put two staples in my head when I wasn't looking,' said Hart.
'He told me he had to do it to stop the bleeding. If he'd have told me what he was doing, I wouldn't have let him so he just shot them in when I wasn't looking.
You can't wash it (blood in hair). I didn't know whether it was a staple gun he was behind me! He glued the one on my forehead.
'I got it (the ball) in plenty of time. It was unfortunate. I say 'unfortunate'but the bottom of his boot caught my head. No harm was done and the ball didn't go in so it didn't really matter.
'I spoke to Petr (Cech) afterwardsbecause he was down after he crashed into the upright trying to keep out Seb Larsson's free-kick. He was very grateful he was wearing his helmet.
Ouch: Hart's head is stapled back together
'He said it saved him because it caught him right on the side of his head. Each to their own but I don't need one at the moment.'
Chelsea enjoyed more chances than most who have turned up at St Andrew's this season. Lampard'sfirst-half effort was kept out by a superb reflex stop by Hart, who brilliantly denied Kalou with a one-handed save.
Alex also fired a thunderous 35-yard free kick against the bar.At the other end, Larsson's free-kick was kept out by Cech and Birmingham had a goal wrongly disallowed for offside when ChristianBenitez sidefooted home.
Ten matches unbeaten for McLeish's side leaves them just one short of a club record, set duringthe 1905-06 season.
'I'm runningout of superlatives for these guys,' said McLeish.
'We keep askingthe question and they keep coming up with the answers.'
What Ancelotti wouldn't give to be able to utter the same sentence in a few weeks' time.
