Hello and welcome to our coverage of the World Cup Group E game between Nigeria and Argentina in Porto Alegre. Nigeria go through with a point but will finish top if they can somehow beat Argentina.

Messi pings the corner into the six-yard box but straight into the arms of Enyeama.

Strong play by Aguero on the far right sees him outmuscle his marker and win a corner.

More lovely link up between Argentina's front three ends with Aguero getting free on the right side of the area but cutting his centre too close to Enyeama.

Head-to-head: Nigeria have lost all three previous World Cup meetings with Argentina. The Super Eagles were also beaten by Paraguay at France 1998, meaning they have lost all four of their World Cup showdowns with South American opponents.

We've had 10 minutes without a goal - what's going on?!

Messi celebrates his opener.

Argentina dictating the play, probing for openings. They look in the groove so far today. Expect more goals.

Another great stat courtesy of Infostrada: Messi is the second Argentinean to score in all 3 (first phase) group matches after Orestes Omar Corbatta in 1958.

Is this Messi's World Cup?

Argentina come again and Messi slips a sensational pass through to Higuain who rounds the keeper but fires into the side netting from a tight angle.

Di Maria shoots from distance but it's straight at the keeper who pushes the moving ball away.

Messi stats.

Messi's strike saw Nigeria concede a World Cup goal for the first time since South Korea's Park Chu-Young scored against them in 2010.

GOAL!!!! What a start! Nigeria are level immediately. Ahmed Musa races into the left side of the area, cuts inside and curls a beauty into the corner. 1-1 inside four minutes!

GOAL!!!!! Messi!!!! It's 3 in 3. Di Maria races onto Mascherano's ball and hammers a shot at goal that ricochets off the post and keeper before falling to Messi who lashes it into the roof of the net.

Odemwingie challenges Mascherano and catches the Barca man's ankle, leading to an early stoppage.

Today’s referee is Italy’s Nicola Rizzoli.

KICK OFF! Argentina get us underway.

COMPARISON: Peter v Lionel.

A shut-out puts Nigeria in the knockout stage - but they'll have to make history...
