After yesterday’s poor performance at the Liberty Stadium where Swansea coasted to a 2-0 win over Newcastle, we take a look at some of the things we learned from the demoralising defeat. The style needs work When Steve McClaren took over at Newcastle, the style of play was one of the key changes that was always going to be made. It was encouraging against Southampton but away from home against one of the slickest teams in the league, it was a huge test in which the Magpies came up short. Swansea have mastered the art of keeping possession and passing teams to death at times but they also couple the smart passing with excellent pressing when they lose the ball, something Newcastle could not get to grips with in South Wales. There was little pressure on the likes of Jonjo Shelvey, allowing him the time to find Jefferson Montero and Bafetimbi Gomis regularly. McClaren nailed his colours to the mast early by picking the same team that drew with Southampton but the style will need months of work before Newcastle can start systematically taking teams apart like Swansea did yesterday. Aggression is a problem Daryl Janmaat’s sending off was both inevitable and ridiculous in equal measure. Two silly challenges on Montero – both well inside the Swansea half – seen the Dutchman dismissed before half-time and leave Newcastle’s chances of getting anything from the game all but gone. An experienced player should have known better and demanded Moussa Sissoko helped him out more with the dangerous Montero and now he will miss the game against Manchester United next week. Aleksandar Mitrovic also picked up his second yellow card in less than half an hour of playtime when he clashed with Neil Taylor. The Serbian is naturally aggressive and won’t be seen shirking a tough challenge anytime soon but the striker is in serious danger of harming the team by running the risk of a red card before his first shot in a Newcastle shirt. A word in his ear from McClaren needs to happen before a hefty suspension and fine land on the Club’s doorstep. Cover at right-back is needed With Janmaat’s sending off comes a problem. Chancel Mbemba filled in at right-back when the Dutchman was dismissed and will be the favourite to get the nod there at Old Trafford next week. Vurnon Anita is another option there but with the diminutive midfielder playing a key role in the midfield, Mbemba seems likely to deputise. Despite the switch seeming simple, it doesn’t cover up the fact that Newcastle have no recognised right-back’s in their squad behind Janmaat. The lack of depth is apparent just two games into the season and having to move a centre-back out to the right and bring in either Steven Taylor or Mike Williamson weakens the defence even more.
