However, as he has often suggested in the past, Messi did admit he would like to return to Argentina "some day".
"We have good players and we are getting stronger to fight as an equal with anyone".
The World Cup is just a few weeks away (!) with sides gearing up for the tournament by playing warm-ups including Argentina.
The Germany squad is training hard ahead of their World Cup title defence in Russian Federation - nearly too hard judging by some of the challenges.
And Messi who won the Olympic gold medal after Argentina beat the West Africans in the final in 2008, bagged three goals in the 17th, 58th and 66th minute of the game. We are not candidates but we are very good, training and improving day by day.

"A friend of mine told me that I'd now be a world champion already if I'd played for Spain, but it wouldn't have been the same", he said.
"It becomes more and more clear that Barcelona will be my only team in Europe".
He revealed (via Sport): "I always said that I want to play some day in Argentine football, I do not know if it will happen, but I have it in mind".
Quoted by the BBC, he said: "We're not going as favourites but will give it our all".
Argentina play Iceland in Moscow in their first match of the World Cup on June 16.
In Russia, Argentina will face Iceland, Nigeria and Croatia in what he called "a complicated group". But that's the way it is, we have to travel on the day before the match, play Israel in Israel and then from there go on to Russian Federation.
Nigeria has qualified to five of the last six World Cups.
