The new boy from Rangers will start with Jerome upfront with the other new face, Nsungu, on the bench.
Speaking of Thompson boss Dave Jones said
'We've been after Steve for some time,' admitted manager Dave Jones. 'He is a quality player, but we mustn't expect him to hit it off immediately.
'If he does that's fantastic, but we have to be patient.
'He has moved from a top Scottish club in Rangers, his wife is expecting a baby in eight weeks and they have to find a home.
'There is a lot to do away from football and we have to sort things out like finding the right hospital for Steve's wife.
'I expect Steve to adapt quickly, but he hasn't played in the Coca-Cola Championship before and he will have to get used to that.
'That will be an eye-opener for him. He is not at full match fitness and needs the next couple of games to sort that out.'
The divisions top two scorers meet head to head at Ninian Park. Jerome and Adi Akinbiyi both have 12 Championship goals this season.
City make changes throughout the team. In defence Glenn Loovens is out so we should see a Cox / Purse partnership. In midfield Jeff Whitley is suspended so Willie Boland is expected to return after injury and Jason Koumas will start after missing the FA Cup match at Highbury last week. And with Lee and Ricketts now gone Thompson and Jerome become the new strike partnership
City possible
Alexander, Weston, Purse, Cox, Barker, Cooper, Koumas, Boland, Ledley, Thompson, Jerome.
With subs possibly Margetson, Darlington, Ardley, Nsungu, Ferretti.
City sit in 10th place, 3 points off the play off places. Burnley are 1 point and 2 places ahead of us. Both teams are doing extremely well this season and are well placed to make a play off challenge.
Burnley come to South Wales with virtually a full strength squad. The only injured player is keeper Danny Coyne who's out with a long term injury. Gifton Noel Williams has recovered from an eye problem and skipper Frank Sinclair will play despite having a broken finger.
Burnley have not won on their travels since last November when they picked up a 1 - 0 win at Leicester. Since then they have drawn two and lost three of the five games played. The Clarets, like City, went out of the Cup last with a 2 - 1 away defeat. Burnley lost at Derby County.
The meeting at Turf Moor earlier in the season ended 3 - 3 with Burnley getting a late leveller. I'd settle for 6 goals again tomorrow but only if at least 4 of them went into Burnley's net.
Kick off on Saturday is at 3:00pm. Tickets are still available today until 5pm and on matchday from the ticket office and ticket booths and you can pay cash at the turnstile for the Bob Bank Terrace.
