FORMER Leeds United 'keeper Neil Sullivan reckons Doncaster can upset the Whites' title aspirations at Elland Road tomorrow.

Ex-Scotland international Sullivan, now in his second season at the Keepmoat Stadium, returns to his old stomping ground for the first time since his move from Leeds.

And he said ahead of the vital Yorkshire derby at the top end of League One: "We have a group of players who are going to enjoy playing in front of 30,000 people.

"We can go there and win. Over the Christ-mas period we were unbeaten in five games - and we've drawn only one of those. Confidence is high and we want to progress."

Doncaster, who last went to Elland Road in 1955, are unbeaten in their last nine away games and quickly sold their ticket allocation for this match of 3,100.

Leeds boss Dennis Wise is keeping tabs on Walsall left-back Daniel Fox, for whom Colchester have had an offer accepted, and Bolton's Slovakian defender Lubo Michalik.

Former Middlesbrough and Derby striker Malcolm Christie is also set to restart his trial spell with Leeds next week. He had been close to signing for the Whites late last year until a back injury postponed talks.

Leeds' game at home to Walsall on March 22 has been selected for Sky television coverage and will now kick off at 5.20pm, not 3pm.
