Smalling went into the season with a question mark over his future at Man United following some indifferent form and injuries but he has really kicked on over the course of the campaign.
The 26-year-old has established himself as a crucial player for United and England and he is now being recognised for his excellent form.
“Chris has improved his passing this season and is able to keep things simple and clean,” Robson said.
“He is excellent in the air and has been one of the best if not the best player at United this season.”
The Englishman is finally fulfilling the potential which convinced United to buy him in 2010 and van Gaal deserves credit for the way he has placed his faith in him. If United sign a quality centre-back in the summer, they would have a promising backline with Smalling, Luke Shaw and one of Guillermo Varela or Matteo Darmian.
