Aston Villa have today confirmed the signing of young Tottenham Hotspur defender Kyle Walker on a loan deal that will keep the player at Villa Park until the end of the season. As first choice right-back Luke Young continues to be plagued by a mystery injury problem, Houllier has acted quickly to bring in a replacement as he looks for solutions to the sides defensive frailties that has Eric Rowe Jersey seen the team concede ten goals in their last four league games, with Villas last clean sheet coming in the dour derby draw against Birmingham way back in October.Walker was signed by Spurs from Sheffield United in July 2009 for undisclosed fee, believed to be as high as 5 million, but was loaned straight to the Championship club where he impre sed last season with a stream of steady performances. Already capped by England at both under-19 and under-21 level, Walker has spent much of this season on loan at trailblazing Queens Park Rangers, where his performances have again Jevon Holland Jersey resulted in much acclaim.Kyle Walker has found opportunities at White Hart Lane limited, and is lookingto prove he has what it takes to succeed in the Premier LeagueThough Walker has only appeared twice for Tottenham in-between his loan spells in the second tier, the young defender firmly believes he has the quality to succeed in the Premier League, and is quoted by the BBC as saying; Im excited about being here and proving that Im good enough to play in the Premier League. Thats why Tottenham bought me and thats what Im keen to show here at Villa.The move however spells bad news for 22-year-old American defender Eric Lichaj, who fresh from signing a new long term deal back in August, now Nat Moore Jersey finds himself as arguably Houlliers fourth choice right-back, behind Young, Walker, and Carlos Cuellar. Lichaj had impre sed against Tottenham Hostpur and West Bromwich Albion in recent weeks, but is no doubt paying the price for an abject display against Manchester City which saw the young defender concede a penalty, and be fortunate not to receive a red card.The signing represents better news for Cuellar however. An 8 million signing from Glasgow Rangers back in August of 2008, Cuellar has been forced to spend much of his Villa career out of position filling in at full-back, or sitting on the bench as others have been picked ahead of him. To Cuellars credit he has never let his obvious frustrations at this spill over into unprofe sional behaviour, and with the relationship between Houllier and Richard Dunne still believed to be at something of an impa se, Cuellar should now be well placed to benefit from a run of games in his natural position.Walkers signing is reminiscent of Martin ONeills move for Phil Bardsley in January 2007Though Walker is not the Jason McCourty Jersey marque signing many Villa fans would have been hoping for, his addition does represent the sensible and restrained approach to transfer dealings that we had been warned by the board to expect. For me the move has something of a familiar feel to it, putting me in mind of Wednesday nights Ghost at the Feast Phil Bardsley, who spent half a Terron Armstead Jersey season on loan at Villa under Martin ONeill back in 2007, when the right-back area was the teams biggest shortcoming. Bardsley was steady yet unspectacular during his time in the claret and blue, though thanks to his late winner on his return to Villa Park he will now be remembered for a different reason. Whether or not Walker is of superior quality to Bardsley, and whether or not he can improve Villas leaky defence, we dont yet know, but with the prospect of the youngster facing his old club Sheffield United in Saturdays third round FA Cup tie seeming likely, we may not have to wait long to find out.
