Is this the best goal ever?
Versatile Borussia Dortmund defender Raphael Guerreiro has marked his return to action with a spectacular training goal that needs to be seen to be believed.
Luckily for lovers of the absurdly outrageous, the club was filming the whole thing.
In what appears a standard training drill, the Portuguese star runs onto a cross. That's where things get interesting.
As he's about to reach the ball, Guerreiro spins around and connects with his heel, sending an angled volley flying into the opposite bottom corner of the goal.
