Michu moved top of the Premier League goalscoring charts as his 13th goal of the season earned Swansea a 1-1 draw with leaders Manchester United after a frantic afternoon at the Liberty Stadium.
Sir Alex Ferguson's side dropped points for the first time this season after scoring first. It is also their first draw of the season, but they were perhaps unfortunate not to depart with all three points after dominating for large swathes of the second period.
Patrice Evra headed home Robin van Persie's corner from close range on 16 minutes only for Spanish forward Michu to level matters when he slipped the ball home after David de Gea had blocked a powerful drive by Jonathan de Guzman.
But a moment of real controversy erupted late on as Ashley Williams struck the ball at the back of Van Persie's head - leading Ferguson to claim the defender "could have killed" his prime striker.
United lead Manchester City by four points after the defending champions completed a 1-0 win over Reading yesterday courtesy of Gareth Barry's headed winner in injury time.
United recorded their first Premier League draw in 20 matches, since the 4-4 home draw with Everton in April, ending their equal-longest Premier League run without a draw.
Michu is one goal ahead of Van Persie at the top of the scoring charts, but the Dutchman would have joined him on 13 goals if a volley had dipped under the bar rather than come back off the top of it from Wayne Rooney's cross on 68 minutes.
Michael Carrick was also desperately unfortunate to see the returning Michel Vorm tip a header onto the bar from a Van Persie corner on 80 minutes as United dominated the second half without finding the winning goal that would restored their six-point lead over City.
In truth, Swansea were worthy of their point on effort alone with captain Williams producing a masterful performance at the back with Kemy Agustien also enjoying a breathless performance at the heart of the midfield for Michael Laudrup's side, who continue to fraternise with a delightful passing game on such days.
Vorm made fine stops to deny Rooney and Ashley Young early on before Evra rose to head into the net off a post as United's early forays forward finally came to fruition.
De Guzman was sent in on goal by Wayne Routledge in the build-up to Michu's equaliser. De Gea managed to repel the midfielder's effort on that occasion before doing likewise nine minutes before half-time.
Evra would pick out Rooney seconds before half-time, but Vorm was again equal to the task in diving low to his left to make a stop.
With the game predictably beginning to open up in the second period, De Gea unearthed competent handling skills to halt efforts by Agustien and Routledge before United assumed control for the last 30 minutes or so.
They appealed for a penalty when substitute Ryan Giggs - who enjoyed a fine little cameo in the closing 12 minutes - supplied Evra, whose cutback fell to Van Persie. Williams made a frantic block to deny the Dutchman while Ben Davies did likewise to half a Young effort prompting United to appeal for a penalty in vain.
Davies also blocked a shot by Antonio Valencia in the opening minutes of the match. Some referees might have awarded a penalty on both occasions, but fortunately for Swansea Michael Oliver wasn't that man as he deemed the effort ball to hand.
It is also worth mentioning the moment Williams walloped the ball off the head of a grounded Van Persie in the second half. Van Persie was furious with the home captain, but both men were booked after being separated by their respective team-mates.
Sir Alex Ferguson was furious with Williams, claiming the ball off the back of Van Persie's header could have "killed him" and is calling for the Swansea man to be banned for a long time.
MAN OF THE MATCH
Ashley Williams (Swansea City): Despite Ferguson's unhappiness with him for apparently intentionally aiming a clearance at the back of Van Persie's head, it was an outstanding display by the Wales international, who seemed to be in the right place at the right time in making a series of superb challenges.
