Shaw, 19, impressed for Southampton last season, earning a place in England's World Cup squad in Brazil this summer before completing a £30m switch to Manchester United. Now, the youngster is expected to be the long-term left back for Louis van Gaal's side after the Red Devils sold Patrice Evra, but his United career hasn't got off to the best of starts.
Having already been told by new manager van Gaal that he isn't fit enough to play, Shaw has now sustained a hamstring injury, which will reportedly keep him sidelined for at least a month. It's a blow for the youngster given that he wants to make an early impact at his new club, but the effects of his injury will stretch further than Old Trafford.
As a result of his time on the injury table, Shaw will miss England's upcoming games against Norway and Switzerland. He may have been in Roy Hodgson's squad this summer, but now his absence opens the door for somebody to take his place – and after Ashley Cole announced his retirement from international football, there is surely only one candidate.
Arsenal's Kieran Gibbs has just three England caps to his name despite being one of the most consistent left backs in the Premier League. Of course, much of that is down to the presence of Cole and now Leighton Baines, but it was something of a surprise to see Shaw handed a spot in the 23-man World Cup squad without much thought given to Gibbs.
Now having put his injury problems behind him, Gibbs made over 40 appearances for Arsenal as he made the left back spot his own – leading to speculation that Spaniard Nacho Monreal would be leaving the club as a result.
Given Cole's retirement and Baines' underwhelming displays at the World Cup, Shaw's absence now presents Gibbs with a golden opportunity. Impress for Arsenal in the opening month of the season and a place in the England squad will be his – and he will even have the chance to push for a starting role as he bids to show Hodgson that Shaw shouldn't be guaranteed of a place in future squads just yet.
