Hearts manager Gary Locke does not expect Celtic to be so generous at set-pieces like they were with AC Milan on Tuesday. Hearts welcome Celtic to Tynecastle on Sunday for their meeting in the fourth round of the Scottish Cup. After Neil Lennon's side had gone almost two years without conceding from a corner, they managed to forget that twice during their 3-0 defeat to the Italian sides as their Champions League hopes ended. However, Locke anticipates the Celtic manager will have used some strong words to pass on the message to his players that they cannot afford any more lapses such as the ones that meant they will finish bottom of Group H.Locke said: "Celtic pride themselves on defending set-plays. I'm sure Neil never saw the goals they conceded coming because they have been really good defensively since the start of the season and have not lost a league game. That will be something he will be working on over the next few days and I don't think we will get it so easy."
