Middlesbrough boss Gareth Southgate admits he could do business with MFK Kosice over two young trialists.
He has been impressed with midfielders Nemanja Matic, 20, and 18-year-old Juraj Hovancik - who have been on trial from Slovakian club MFK Kosice this week - and Boro are now looking into the financial aspects of any deal.
Southgate said: "The older lad was only in for a couple of days - he has met up now with the full national side [Serbia].
"They have both done very well. It's difficult with triallists, because ideally we want to see them again now in their own environment playing in matches.
"But we have been impressed with them. We have got to see what finances are involved in bringing them here."
