Gary Neville has questioned England manager Fabio Capello's decision to pick Liverpool's Glen Johnson as his sole right-back for the World Cup.Johnson has established himself as England's first-choice right-back under Capello, but suffered an injury-interrupted second half of the season. [LNB]And Neville said: "I'm surprised there is only one right-back in the squad." [LNB]Neville also labelled attempts to lure Paul Scholes out of international retirement "a bit desperate". [LNB]Despite failing in his attempt to bring Scholes back into the England fold, Capello did persuade Liverpool's Jamie Carragher to return to the squad three years after his own international retirement.[LNB] Carragher retired because he was being overlooked by players who were no where near as good as him... he is a great player and I am happy he is in the squad chris And although Carragher has played the majority of his career at centre-back, his ability to cover either full-back position was seemingly key in Capello's decision to overlook Manchester United's Neville and Wes Brown. [LNB]However, Neville argued that Brown, who started at right-back when England beat Egypt in their last fixture as Johnson recovered from knee ligament damage, was unlucky to miss out. [LNB]"I wouldn't say I'm overly disappointed not to be named in the initial 30-man squad, although I did think there was maybe a chance I could get in," added Neville, who made 15 Premier League starts last season but failed to add to his 85 England caps. [LNB]"I'm probably more surprised Wes Brown isn't in the 30, to be honest." [LNB]Scholes, who retired from international football in 2004, appeared set for a return of his own before eventually rejecting Capello's overtures.[LNB] [LNB][LNB]World Cup guide - England[LNB]And Neville admitted that courting Scholes made sense, even if it was unlikely to succeed. [LNB]"I'm not surprised Capello tried to get him out of retirement because if there's one player I would try to pull out of retirement it's Scholes," Neville said of his team-mate and fellow 35-year-old. [LNB]"Capello maybe got a bit desperate at the last minute and wanted Scholes because he's still probably the best midfielder in England, but Scholes decided to stick to his guns." [LNB]Meanwhile, Manchester City have confirmed that midfielder Gareth Barry has been sleeping in an oxygen tent in an attempt to speed up his recovery from an ankle injury. [LNB]Capello remains hopeful that Barry will be fit for England's second World Cup group game against Algeria on 18 June. [LNB]Before that the Italian is set to assess defenders Ledley King and Jamie Carragher in the sold-out friendly against Mexico at Wembley on 24 May. [LNB]Neither have played for England since the end of Steve McClaren's reign in 2007.
