Sky Sports pundit Alan Smith believes that Tottenham defender Kyle Walker used to lack concentration, but is now in his best ever form under Mauricio Pochettino.

The 26-year-old has become a crucial player for Spurs in recent years and has helped them up to second in the Premier League this season.

He has been an ever-present in the right wing-back position this campaign and is in the squad for England during the upcoming international break.

Walker has made 32 appearances this season across all competitions and has been one of the club’s most consistent performers, but has not always been the first-choice option.

He moved to White Hart Lane in 2009 and was loaned out Sheffield United, QPR and Aston Villa in the earlier stages of his career.

Ex-Arsenal striker feels that Pochettino has been able to help Walker with certain areas of his game to make him the player he is now.

“Walker is in the form of his life under Mauricio Pochettino at Spurs,” Smith told Sky Sports. “He used to be guilty of lacking concentration but he’s addressed that over the last two seasons.”

Walker is now regarded as one of the best full-backs in the Premier League and one of the most athletic, with Danny Rose occupying a similar role in Spurs’ left-back slot.

The defender has been given a more attacking licence this season in Spurs 3-4-3 formation and has chipped in with six assists so far.

He is under pressure from team-mate Kieran Trippier for a starting position, but is a permanent fixture in Pochettino’s starting XI.

England boss Gareth Southgate is expected to use Walker as his right-back going forward and it shows how far he has grown with Spurs in recent years.
