Paulo Sousa has become the latest victim of QPR's managerial Tourette's - having been shown the door after just 26 games in charge at Loftus Road. Although the Portuguese coach took charge of training this morning (Thursday), he was later told his services would no longer be required and Gareth Ainsworth has been entrusted with first team affairs for the rest of the season.  The increasing impatience of the owners to hit on a winning formula has now led them to show the door to John Gregory, Luigi Di Canio, Iain Dowie and Sousa in the two and a bit years they have been in control – not to mention caretaker bosses Mick Harford last season and Ainsworth five months ago when he had his first spell in charge as caretaker. Although Sousa recently brought an end to a winless streak of nine games with back-to-back home wins over Swansea City and Bristol City, the damage had been done to the team's play-off hopes. Hailed as a bright young prospect when he was first unveiled by chairman Flavio Briatore, he was no longer in favour. A run of one goal in six games along with home defeats by Ipswich Town in front of Sky cameras and then by Norwich City may have embarrassed Briatore into looking for a way out. And they found one when Sousa made it clear he had nothing to do with the departure of top scorer Dexter Blackstock to Nottingham Forest two weeks ago. By hinting he had been undermined, he would have infuriated the hands-on owner, who may also have picked up on internet message board claims that Sousa was allegedly indiscreet in telling a fan that the players at his disposal were not quite up to the task. But equally, his attempts at educating the players to formations alien to their English footballing habits may have made his task harder. This morning, sporting director Gianni Paladini was claiming he knew nothing of an imminent departure of the two-times European cup winner, but behind the scenes, the axe was ready to drop. Rangers planned to review Sousa’s position at the end of the season and decided that his right-hand man, Bruno Oliveira, should initially carry the can for the club’s failure to reach the play-offs. But having been given that stay of execution, Sousa was left to decide whether he wanted to carry on in light of Oliveira’s sacking. Sousa's reign was not helped by ill fortune on the injury front. Several key players have not been at his disposal at various times since his arrival in November last year. Akos Buzsaky, Rowan Vine, Martin Rowlands and Patrick Agyemang have all been sidelined. But in all probability, only reaching the play-offs would have spared him a similar fate to his predecessors.
