"We've tried hard to get a striker," he told Hearts News Today.
"We made a few enquiries about boys who were not available in the end.
"We agreed with the owners about the striking position but it had to be the right one.
"Bringing someone in for the sake of it would not have worked.
"For now, we go with what we've got and we'll come back to this in the summer."
Meanwhile, a minute's silence has been arranged prior to kick-off of Hearts' Co-operative Insurance Cup semi-final against St Mirren at Fir Park on Tuesday night..
It was set up in memory of former Jambos player Bobby Kirk, who passed away on Monday at the age of 86.
Kirk played for Hearts between 1955 and 1962, helping the club beat Celtic in the 1956 Scottish Cup final.
