The 25-year-old is enjoying the best season of his career, scoring 10 goals and registering eight assists for the eighth-placed Saints and pushing his case to go to the World Cup with England.
The club captain created his team's second goal and scored the magnificent third at St Mary's Stadium on Saturday as the hosts smashed Newcastle 4-0, with the Argentine waxing lyrical about his ability.

"I am always telling him that he has the characteristics of a Spanish player and he has the skills of an Iniesta, Xavi or Fabregas."
Southampton started the second half against Newcastle 1-0 up and two pieces of brilliance from Lallana saw them stretch that lead to 3-0 by the 70th minute.
The attacking midfielder produced a sublime chip over the visiting defence for Rickie Lambert to score in the 49th minute before the skipper later blasted home from over 20 yards.
"Adam is special, he is a very unique player," Pochettino added. "There is not another player in the country like him."
