Manchester United icon Dwight Yorke says Roberto Mancini needs to draw a line in the sand at Manchester City over Carlos Tevez's sulk.

Former United striker Yorke believes Mancini has some work on his hands resolving an awkward situation with a player who is lavishly paid at City and would be affordable to only a small number of top clubs.

"I don't condone what he's done, in terms of refusing to go on the pitch. No-one likes to see that," said Yorke.

"We don't know the ins and outs but they need to sort that out. You don't need that around the place.

"The manager has got some work to do and he alone can make those decisions."
