'Unbelievable' debut delights Mata

Juan Mata says his Manchester United debut was "unbelievable" following the champions' 2-0 win over Cardiff at Old Trafford.

The Spanish international became Manchester United's record signing when he completed a £37.1m move from Chelsea on Sunday.

Ashley Young's spectacular goal secured the points after Robin van Persie's opener and Mata says United "will try until the end" to gain a Champions League spot.
