Tony Pulis was in the middle of a textbook post-match debrief — short, sharp, with no words wasted — when his train of thought was interrupted.
From the corner of his eye, he caught the hulking figure of Jurgen Klopp marching purposefully towards him. When Pulis was last at Anfield, in December 2015, the two managers had been embroiled in a heated touchline squabble and the fall-out lasted long after the final whistle.
This time, though, there was no animosity. Klopp had sought out his opposite number to shake his hand after his side had been taken to the wire by West Brom.
