Johannesburg - Kaizer Chiefs coach Vladimir Vermezovic has hinted he may rest star winger Siphiwe Tshabalala for Sunday's trip to sixth-placed Santos.Amakhosi, who claimed second spot on the Premiership table following a 1-0 midweek win over neighbours Moroka Swallows, will face the Capetonians at Athlone Stadium.And while Chiefs are determined to trim Orlando Pirates' two-point lead at the summit, Vermezovic says he is considering giving Tshabalala a break."There will be some changes to the team," he said after Wednesday night's Soweto derby at Loftus Versfeld."For 'Shabba', this was his fourth game in a short space of time. He also played for Bafana, so we must be careful of tiredness."Regarding the title race, the Serbian added: "We are two points behind Pirates, but Ajax and Sundowns are also there. The race will be very interesting as there are still lots of games left."Tonight we will take a break and then tomorrow we will start preparing for Santos."Vermezovic's preparations will be hampered by the unavailability of defender Dominic Isaacs and playmaker Mthokozisi Yende. Both players will serve one-match bans after receiving their third caution of the campaign against Swallows.
