MANCHESTER United had to settle for a point against Chelsea after the hosts came from behind at Stamford Bridge.

Park Ji-sung scored after 18 minutes and the Reds looked set to break Chelsea's 84-game unbeaten home record in the league.

But substitute Salomon Kalou scored after 80 minutes with a header after he was left unmarked to ensure the game ended all square.

Not for the first time in his illustrious career, Reds boss Sir Alex Ferguson’s team selection caused an outbreak of head scratching among United’s army of fans.

Yet his choice of Park and Darren Fletcher worked a dream, especially with the Scot switching to the middle of midfield, a move that saw Owen Hargreaves take up a right-wing station.

Identifying Chelsea’s full-backs Jose Bosingwa and Ashley Cole as major attacking threats, Ferguson chose to put his two most energetic men in direct opposition, keeping the home pair occupied defensively and stifling their threat in attack.

Despite their poor recent form, the Reds showed their attacking intent from the start, when Fletcher turned Hargreaves’ low cross wide, and Chelsea, having lost Deco just before kick-off after the Portugal star was injured in the warm-up, could not get into their stride even though they could call upon Michael Ballack as replacement.

Luiz Felipe Scolari’s team was further disrupted when Ricardo Carvalho hobbled off after just 12 minutes, so there was always a nagging fear Joe Cole’s failure to find the net when he robbed Patrice Evra to give himself a clear sight of goal was going to prove costly.

Chelsea, already given one let off when Petr Cech’s wayward clearance gave first Dimitar Berbatov, then Wayne Rooney the chance to launch speculative efforts at the home goal, survived again when Rooney set up Ferdinand, only for the home keeper to save with his legs.

But on their next attack, United finally prospered as Patrice Evra galloped past Bosingwa to reach Rooney’s inspired through ball.

Evra’s pinpoint cross found Berbatov and while Cech was once again equal to the shot, Park had the easiest of tasks to bundle home the rebound.

After spending nearly half an hour on the back foot, Chelsea finally got into their stride.

Gary Neville’s back header spread panic in the visitors defence and when Edwin van der Sar came off worst in a collision with Florent Malouda, who might easily have scored, the veteran Dutchman was eventually forced from the field.

Chelsea’s improved performance also brought out the spikier side in Paul Scholes, who was booked, although, with Nicolas Anelka also firing over on a couple of occasions, it was not until the arrival of Didier Drogba - following a brief delay due to an offending bracelet - that the home side really upped the ante.

Ferguson’s response was to bring on Cristiano Ronaldo, who put the Chelsea defence on red alert with his direct running but also shamed himself with a blatant dive as Frank Lampard made a tackle.

But just as a wobbling Chelsea had eventually tumbled in the first-half, so United did the same 10 minutes from time.

In chopping down Ashley Cole, Rooney not only picked up his side’s fifth booking. He also provided John Mikel Obi with the opportunity to float over a free-kick to the edge of the United six-yard box where the visitors, getting their marking and offside trap hopelessly wrong, left Kalou on his own to nod home the equaliser.

The game ended in bad tempered fashion as United, who had seven players booked, complained bitterly at referee Mike Riley for his handling of the game as Drogba was receiving treatment after being clattered by Ferdinand.
