Sunderland have only scored one goal so far this season, having been held to a 0-0 draw by Swansea on Saturday. Bruce has already signed two new strikers in Ji Dong-won and Connor Wickham, but the Black Cats boss sees them as players more for the future. Bruce accepts Darren Bent has still not been adequately replaced following his move to Aston Villa in January and, with Asamoah Gyan currently out of form, another striker is top of the club's shopping list. "We've brought in Ji and Wickham as players for the future - we were delighted to have the opportunity to get players of their potential in - but we won't see the best of them for a year to 18 months," Bruce told the Sunderland Echo. "In the meantime, we need a bit extra up front. "If we're honest, we've been lacking a bit in that department since Darren Bent left in January and we know that. "So we'll be doing all we can to bring someone in in the next few days - we just have to wait and see what happens and whether anything can be done."
