The left back spot of the Super Eagles of Nigeria is one area where options have been limited for various handlers of the team with most coaches sticking to Elderson Echiejile.
As steady as Echeijile is, he still divides opinion among fans of the team with many viewing him as the weak spot of the team in the last few years.
Now playing for Sivasspor of Turkey, the 27 year old is having a real battle to hang on to his spot for the first time in three years following the emergence of Chelsea full back Ola Aina.
Although Aina is more comfortable as a right back, he played admirably well as a left full back when he replaced Echiejile in the Eagles 1-0 win over Zambia, which sealed their passage to the World Cup in Russia next year..
Aina will further make his case to replace Echiejile as the right back of the Eagles when they play Algeria tomorrow in a dead rubber World Cup 2018 Qualifiers with Echiejile absent through injury.
Coach Gernot Rohr will also have another option in that same spot to pick from on Tuesday, when they take on Argentina in a high profile friendly with Russian-Nigerian left back Brian Idowu set to join the team in Russia.
The Amkar Perm defender is an out and out left full back well grounded in the area of making tackles and also solid in aeria duels, his pace and ability to whip in crosses will no doubt affect the chances of Echiejile hanging onto his spot.
