Cape Town - Kaizer Chiefs coach Stuart Baxter admits his side were not at their best against Mpumalanga Black Aces, but was still pleased to close out the year with the three points. READ: Masango heads Chiefs to victory.Amakhosi made it 18 Premiership matches without defeat this term as Mandla Masango's lone strike secured a 1-0 win over AmaZayoni at the FNB Stadium on Saturday, leaving Chiefs 15 points clear at the top heading into the two-month break.However, Baxter feels the Glamour Boys are much more capable than they showed against Black Aces, telling his club's official website: "We can play better."He did, however, admit his relief at closing out the first-half of the campaign on a high, adding: "But I am happy with the three points. We didn’t want to finish the year on an anti-climax."The coach also made special mention of Ivan Bukenya's performance on the day, saying: "In the second half, we had better off-the-ball movement. Ivan Bukenya played almost like a third centre-back, sitting very deep. It encouraged me to play with three centre-backs after we went 1-0 up."We were worried that we would struggle in the defensive midfield role after Willard Katsande got injured. But Ivan has raised his hand, doing well in the two matches that he started and he should be applauded for that."
