Argentina fields Messi-led 4-3-3 against Nigeria
PORTO ALEGRE, Brazil—Nigeria and Argentina are not resting any of their starters in their final Group F match on Wednesday and sticking with the lineups they had in their previous matches.
Argentina will again rely on captain Lionel Messi — with two World Cup goals in Brazil already — moving wide and deep in a three-man attack behind Sergio Aguero and Gonzalo Higuain.
Nigeria coach Stephen Keshi is also keeping the lineup he used in Nigeria’s previous match, against Bosnia-Herzegovina.
Vincent Enyeama will try to remain the only goalkeeper yet to concede a goal at this World Cup, while striker Peter Odemwingie has been called up again after scoring the winner against Bosnia.
Already qualified for the second round, Argentina needs at least a draw to win Group F. If Nigeriawins it will top the group, while a draw is enough to make sure of advancing.
Nigeria: Vincent Enyeama; Efe Ambrose, Kenneth Omeruo, Joseph Yobo, Juwon Oshaniwa; Ahmed Musa, Ogenyi Onazi, John Obi Mikel, Michael Babatunde; Peter Odemwingie, Emmanuel Emenike.
Argentina: Sergio Romero; Pablo Zabaleta, Federico Fernandez, Ezequiel Garay, Marcos Rojo; Fernando Gago, Javier Mascherano, Angel Di Maria; Lionel Messi, Gonzalo Higuain, Sergio Aguero.
