Michu strike gives Swansea cutting edge over Chelsea after 2-0 Capital One Cup semi-final first leg victory They chanted Lampard's name until he eventually came on. They chanted the name of Demba Ba until he eventually replaced Torres. Benítez could have made his changes earlier; the memory endures of Jose Mourinho being far more decisive with his substitutions. Benítez was outwitted by Michael Laudrup, who set Swansea up superbly, almost as a classic counter-attacking team, as if preparing for Europe. When Chelsea had possession, which was for long periods of the game, Swansea pressed hard, then dropped deep, manning the barricades with only Michu left up. Laudrup's creative wide players, Wayne Routledge and Pablo Hernández, tracked back time after time to cover their full-backs. Angel Rangel and the calm teenager Ben Davies threw themselves into blocks, working hard to stop Chelsea crosses at source. In the centre, Ashley Williams was immense, dominating the air (albeit predominantly against a tepid Torres), and a model of concentration and commitment that set the tone for his team. Here was a real leader, again demonstrating the character that Chelsea need more of. Alongside Williams, Chico Flores even found time to deal with a pitch invader. Leon Brittain kept moving the ball forward, occasionally darting past David Luiz. Jonathan de Guzmán broke forward, looking to link with Michu. Praise needs bestowing on Laudrup as well as his players. He set Chelsea problems with his starting line-up and tactics and then set them more problems with his changes, particularly sending on Graham, who harried Chelsea's defence and took Swansea's second goal well. Swansea's prominence has inevitably stirred speculation as to whether Michu will leave - and he probably will in the summer for a substantial fee - but the club will also beware suitors for Laudrup. He has been one of the managerial stars of the season and if he leads Swansea to the final his stock will soar higher than the famous arch. Chelsea had their chances but seemed almost obsessed with over-elaborating. It was all pass, pass, pass, all style but no substance. They enjoyed a wonderful opportunity early on, the ball flowing from the captain Ashley Cole to Juan Mata, Luiz and Oscar and then on to Eden Hazard. The Belgian played in Ramires, who delayed his shot and eventually stabbed a weak effort straight at Gerhard Tremmel. Still Chelsea sought to find a way through. Mata (twice), César Azpilicueta and Gary Cahill had chances but failed to trouble Tremmel. Such profligacy was then punished by Michu, striking his 16th goal of the season. Ross Turnbull, such an inexperienced understudy for Petr Cech, hardly did Ivanovic any favours with his ball out, although the Serb was still culpable. He dawdled, De Guzmán nipped in and Chelsea were punished. The striker calmly swept the ball past Turnbull from the edge of the area. Ivanovic immediately sought to make amends, charging forward and unleashing a strong shot that Tremmel did well to push away. After the break, Chelsea again tried to turn all their possession into something tangible. Luiz was denied by Tremmel. Still the calls for Lampard came and he arrived with 20 minutes left. Still the clamour grew for Ba to replace Torres. When Oscar crossed from the right, Torres was too static, Tremmel cleared with his feet and Benítez had seen enough. Ba bounded on much to the delight of the Chelsea fans, who immediately saw the new striker twice go close with headers. Chelsea continued to do so little with so much possession. A Lampard strike was well saved by Tremmel. Luiz also blasted the ball over. Ba then ran through but was harshly deemed to have dived when it seemed a simple collision with Tremmel. Referee Anthony Taylor crazily then cautioned a disbelieving Ba. Chelsea's evening continued to dissolve into a nightmare. Ivanovic played the ball back blind to Turnbull, almost in a ghastly reverse of their first-half aberration. Graham pounced, rounded Turnbull and stroked the ball home past the sliding, despairing Ivanovic and Cahill. Ivanovic beat the pitch in frustration. When Ba was wrongly ruled offside on drilling the ball into the net, the nightmare deepened for Chelsea.
