With just a point from its two games, Argentina is in dire need for its talisman to fire against its final group stage opponent Nigeria and ensure a longer stay in the quadrennial event. "I asked him to play [for another club] so he would have the rhythm of the matches".
Defender Brian Idowu, who joined his coach at the news conference, said Nigeria's only choice was to try and bring Messi's World Cup to an end.
A World Cup without two-time champion Argentina was a real possibility around October 2017.
After using a 4-2-3-1 formation against Iceland and a 3-4-3 versus Croatia, Argentina are expected to change once again, with a 4-3-3 or 4-4-2 expected.More news: Toronto Pride Parade to kick off amid tensions between LGBTQ community, police
Argentina are now enduring their longest winless run in World Cup finals history (D2 L2) and have never previously gone through a first-round World Cup group stage without at least one victory before.
Should Iceland defeat Croatia, they can still advance under the scenario of beating Nigeria and winning their tiebreaker against Iceland.
"I don't know if I will play or not because I couldn't get enough time against Iceland but the most important thing is for us is to get the result".

"That match was complicated for Messi because the structure of the game didn't favour him", he said.
Against the tricky Icelandic team, he took his opportunity with both hands by scoring two goals to help the Super Eagles win and keep their slim hopes alive. "We are determined to win this game and reach the last 16". Messi scored twice when Argentina beat Nigeria 3-2 in the group stage four years ago. We don't know what are true, what are lies, there are so many people speaking.
"It is the most critical situation I have experienced, along with the Ecuador game", said Argentina midfielder Lucas Biglia on Sunday.
The team's German manager Gernot Rohr praised their "humility, solidarity and fighting spirit" so far in the tournament, believing his young squad has a good shot at victory over Argentina. "The question is not if it is the last World Cup for him or not, the question is for us to be qualified".More news: Harley-Davidson Announces Overseas Move, Cites Tariffs
