Could set-piece coach lured from Hearts be Celtic's key signing?

More than a third of their league goals came from set-plays, while no team managed a higher tally than their total of 23. Rangers were joint top with Hearts in that chart; Celtic were around mid-table.

Sixteen of those 23 Hearts goals came from corners - a league high. Celtic had 10 fewer, with just six - only two teams had a worse tally.

By a distance, Hearts had the most successful corners into opposition boxes and the most aerial duels won. They also created the most chances from set-plays. Celtic were eighth in that regard.

Hearts scored six goals fewer than Celtic but had double the number of headed goals, with striker Claudio Braga and centre-back Stuart Findlay nodding in the most in the division - five each.

Defensively, only two teams conceded fewer goals from set-pieces than Hearts. One of those sides was Celtic, who conceded nine to Hearts' 10.
