Manchester United left-back Luke Shaw has claimed he wants to "show people why" this summer he earned a move to Old Trafford.

Manager Louis van Gaal made the England international the world's most expensive teenager after paying an initial fee of £27m which could rise to £31m based on future successes.

Having garnered a reputation as one of the most promising prospects in the Premier League during his time at Southampton, the 19-year-old was expected to fill the void left by the departure of Patrice Evra to Juventus.

However, the English international's adaptation to Old Trafford has been hampered by a number of injuries during his debut season at the Premier League giants.

The former Southampton academy star has indeed only managed to start 12 games this season while in the Monday's FA Cup defeat against Arsenal he was replaced at half-time because having missed the previous two games against Newcastle and Sunderland he was reportedly not 100% fit to play the full 90 minutes.

Shaw, however, has claimed he is enjoying his time at Old Trafford and promises to keep progressing in order to prove why during his time at Southampton he was considered one of the next big things to emerge in English football.

I appreciate I've been lucky to be my age and to have gone to the World Cup, and to be where I am now. It's just unbelievable," Shaw said to United review. "[But] I'm not taking anything for granted. I just want to keep on improving as a player and show people why I am here at Manchester United."

And even though he was born in London before moving to Southampton he claims he already feels like Manchester is home.

"I love it. It's a nice place to be," he says. "I've settled down in my house and it's nice and quiet. I'm with my family and have a couple of friends up here, so it just feels like home."
