Sky Blues take look at duo
Sky Blues boss Gary McAllister is keen to bolster his squad as he plans a promotion push in the second half of the season.
He wants to look at Argentine star Sara and former Manchester City midfielder Karim Kerkar before deciding to offer them deals.
"Juan Sara has come in for a few days just to get a feel for the place and if he impresses and if all things are equal we're looking to maybe offer him something until the end of the season," said McAllister.
"He's another experienced striker who has scored goals in the Scottish Premier League.
"He's just here visiting because it's the winter break in Scotland at the moment."
Kerkar is looking for a new club after being released by City last month
"We've got Karim Kerkar, who was at La Havre and came over on loan to Manchester City with Ali Benarbia.
"They have not offered him anything after a short-term deal so we're having a look at him too."
