According to influential Serbian sports website, sportal.rs,&nbsp; Red Star Belgrade are in the market for reinforcement in midfield and have beamed their searchlight on two Nigeria internationals - Enugu Rangers' Sunday Mba and Fegor Ogude of V&aring;lerenga.<br /><br />Sports Director of the 1991 European champions, Zoran Stojadinovic hopes to conclude the signing of one of the two players before the end of August.<br /><br />After February's African Cup of Nations, Sunday Mba, 24 , was linked with FC Karpaty (Ukraine) and Romania big spenders CFR Cluj but the ownership tussle between Enugu Rangers and Warri Wolves threw the spanner in the works.<br /><br />On the other hand, this summer, Fegor Ogude has been courted by Real Betis and Sporting Lisbon. <br /><br />However, according to the player's agent Atta Aneke, none of the clubs have backed up their interest with an official bid to V&aring;lerenga.<br /><br />Last month, Red Star launched a bid of 200,000 euros for another Nigeria international Azubuike Egwuekwe.<br /><br />But it was well short of the center back's valuation of around 350,000 euros, so Warri Wolves turned down their proposal.<br /><br /><br />
