The Bafana Bafana back believes that their major problem has been a failure to convert chances - something that is well documented.
The statistic do not lie either with United scoring just once so far in their four games. This despite being one of the most creative teams in the league, with nearly 50 chances carved out in their 240 minutes of action.
"We are disappointed about the results of the last four games," Xulu says. "But obviously it's something that we are working on as a team, to convert the chances we create. Scoring is a worrying factor for us at the moment, but we are confident of a turnaround."
According to the KwaMashu-born star, the club is using the FIFA break productively to sharpen the boots in the final third.
"We are working very hard in our final third," Xulu adds. "In the couple of matches we played towards the end of last season we were doing very well with scoring goals, now we have to redo that.
"Right now, it's just one factor that we are lacking in and we are doing our best to find solutions to score goals."
The Team of Choice recently signed Jeremy Brockie on a season-long loan deal from Mamelodi Sundowns and Xulu is confident that the New Zealander will add value to the club.
"He is a magnificent player," Xulu adds. "I'm very happy that coach Eric Tinkler, the one who brought the best out of him at SuperSport United, will be working with him again. "It's going to be very good for us the fact that they both worked together. He is going to help us a lot and and we are very excited to have him in the club."
United's next match is a trip to Tshwane to take on Sundowns on Saturday, September 21.
