Head coach Steven Schumacher had a frustrating start in charge of Stoke City as fellow Championship strugglers Millwall survived a second-half onslaught to earn a point.
Both out-of-form sides struggled in a dismal first half, with the Lions not managing an attempt on goal until first-half injury time when Jake Cooper headed wide, and the hosts not faring much better.
But Schumacher, who only left Plymouth Argyle to replace Alex Neil as Potters boss on Tuesday, clearly made an impact during the half-time break as the Potters piled forward trying to end an eight-game winless run.
Countless chances went begging, with Ryan Mmaee and Josh Laurent both going close, while Lions keeper Matija Sarkic was also in inspired form.
