Turkish referee Cuneyt Cakir was the scapegoat for Manchester Uniteds exit in Champions League. This time, the Red Devils have no one but themselves to blame. They blew away their two-goals lead at home and was beaten by another big Chelseas second half in the FA Cup replay at Stamford Bridge.An unusual Monday lunchtime kickoff sent the players back in action after only 48 hours of rest, while Chelsea even has the Europa League on Thursday in mind. After the embarra sing defeat at Southampton, Juan Mata, Eden Hazard and Ramires were all back in the starting lineup to supply Demba Ba. On the other hand, Sir Alex Ferguson had the luxury to field fresh Danny Welbeck and Javier Hernandez, while resting Robin Van Persie on the bench and nursing Wayne Rooneys groin problems.Neverthele s, it was obvious how important their two best strikers are to the league leader. United dominated the first half but was never close to clinical. Phil Joness involvement helped ease the workload of Michael Carrick, who played his second game in three days, and also quieted the trio of Mata, Hazard and Oscar, but Nanis inability to pa s could not translate the solid midfield performance into goals. Javier Hernandez had to do it on his own, but his rare long shot was kept out by Peter Cechs leg, although the Czech looked to have dived to his left a split second earlier than needed. It was the best, and almost the only chance of Sir Alexs side in the first half.Chelsea looked yet to rediscover the fluency and confidence in their Jose Quintana Jersey football. Ashley Coles pull-out due to injury further weakened their defence, though luckily untested as Nani was struggling all day long. Ramires and Mikel lost in the battle of po se sion and there was little scope for their playmakers to create.Just when one would expect another unconvincing but narrow victory for Manchester United, a quality goal of world-cla s calibre changed the dynamic of the game. Juan Mata found some rare breathing space and sent a perfectly-measured pa s to Demba Ba, who ran over Rio Ferdinands shoulder and skilfully guided his first time volley to the far corner, that left the in-form De Gea stand and stare at the ball helple sly.Three minutes into the second half and Chelsea found themselves in the lead via a goal that came from absolutely nowhere. They needed more than that to make Demba Bas goal count and Peter Cech had delivered what they needed. Hernandez beat the offside trap and connected with Danny Welbecks cro s. He sent his header to the wrong side of Cech, but somehow Cech managed to Brad Wieck Jersey tip over his header with his left palm while diving to his right. It was a save that amused the stadium and certainly earned more than the appreciative smile from the Mexican forward.Alex Ferguson pre sed on by sending in Robin Van Persie and Ryan Giggs, but it did not sharpen Uniteds attack at all. Patrice Evra found no companion down the left flank, which was filled up by Tom Cleverley before he was substituted. Moving Phil Jones to the right back left Michael Carrick all alone in midfield, as Giggs was slotted into the free role just behind Van Persie and Hernandez. All of a sudden, Chelsea won back the control of midfield. Mata was liberated and came alive again . He first tested De Gea with a near post shot, then sent an unmarked shot to the wrong side of left post. The increasing pre sure had also sent the ever calm-looking Carrick buckled. A poor back lob pa s was intercepted by Eden Hazard, who burst through Ferdinand and Phil Jones but wastefully misfired the opportunity that could have sealed the match.When Alex Ferguson restored the balance of the formation by introducing Ashley Young, there were only ten minutes left for their search of equaliser. They still managed to create two chances, both from left flanks, but there was no Upton Parks magic this time from Robin Van Persie. The fans would be disappointed by the left-footed volley he mi sed, the type of shot he has been delivering all year long, while Sir Alexs late substitution could be even more frustrating.Twice being the underdog of the matchup, and having just had a miserable Saturday, Rafa Benitez proves once again he is the cup specialist. They have not played the entertaining and pretty football Abramovich has invested for, but determined tactical change and stellar defence were the keys to their succe s this season in both local and European cups. Having failed to get the better of Manchester City this season, a semi-final victory at Wembley two weeks later may see the fans-jeering target re-emerge as a serious contender for the permanent job at Stamford Bridge.
