Ramírez - 22 a month ago - is quickly becoming the jewel in Saints' crown of young and exciting footballers. As we enter 2013, though, the attacking midfielder insists the best is yet to come.
"I feel like it is time for me to 'explode', if you like," Gastón told Saints' official matchday programme.
"I believe I am getting better with each game. I feel like I'm improving a lot because I'm playing a lot of games, so I'm getting used to the kind of opposition you face here.
"I've loved my first five months at Southampton and I feel very happy here."
