As another year draws to a close and clubs prepare for either a winter-break or a busy set of festive fixtures, it is time to take a step back and look at how players have grown in stature in 2017.While Individual awards are well and good, they do not paint a full picture. The FIFA FIFPro XI turned out to be a popularity contest and did not reward certain players who deserved to be recognised.Therefore, we look at the players that would constitute the Most Valuable XI of 2017.Formation: 3-5-2. Data: TransferMarktGoalkeeper: David De Gea (Manchester United)A number of goalkeepers are valued very highly in the market today and none more so than Manchester United's David De Gea. Just ask Real Madrid - who saw a deadline day deal for the Spaniard scuppered due to various technicalities.The move hurt De Gea and he responded by extending his own contract at Old Trafford. Back then he was valued at €30m but the 27-year-old is now valued at €40m. But good luck submitting a bid that low to secure his services.De Gea has proven time and again that he is arguably the best goalkeeper in the Premier League. His form is the primary reason Manchester United have conceded the least number of goals this season.And his memorable performance against Arsenal at the Emirates will only make Real Madrid wish their fax machine had been up and running back in 2015.? @D_DeGea made 14 saves against Arsenal, the joint-most by a goalkeeper in a single #PL match alongside Tim Krul & Vito Mannone#ARSMUN @ManUtd pic.twitter.com/GptDYx7cce— Premier League (@premierleague) December 2, 2017
