Swansea produced a consummate display of attacking football at Wembley to secure a 5-0 win over 10-man Bradford in Sunday's Capital One Cup final at Wembley.
Man of the match Nathan Dyer (two), Jonathan de Guzman (two) and Michu got on the scoresheet to the delight of the 33,000 Swans fans who had made the journey to London.
When Laudrup succeeded Brendan Rodgers at the Liberty Stadium last summer, the doom-mongers were predicting a season-long battle to retain their top-flight status.
But, after a blip at the start of September, the Dane has guided the club into the top half of the Premier League and to within one win of reaching their survival target of 40 points.
Sunday's unprecedented triumph at Wembley only adds to the lustre of what must rank as the greatest season the club have ever known.
Attention will inevitably turn to whether Laudrup ignores the string of reported suitors - among them Real Madrid, who he represented as a player - keen to secure his services and remains in south Wales beyond the end of the season.
Whatever happens, Rangel is in no doubt Laudrup's achievements deserve to be recognised. He said: "I would say he 100 per cent deserves to be manager of the year. If we stay in the top 10 having won the cup, I think it is just about the best Swansea can achieve and from our point of view he has to be the best.
"He has made a big difference, when he came here he knew we could play football, but we lacked the cutting edge to score lots of goals and create chances. We are more aggressive in attack now. We create more chances, we are really comfortable and the team is very balanced."
