Well are unbeaten in their last three home matches.
Motherwell goalscorer Danny Johnson felt they “rattled” Celtic during Wednesday’s 1-1 draw at Fir Park.
Celtic went ahead early on when Ryan Christie netted as Well were briefly down to 10 men after losing their second defender to injury.
Hoops defender Filip Benkovic had a goal disallowed and Mark Gillespie saved a Leigh Griffiths penalty, with Motherwell struggling to create chances until the final 10 minutes.
But Celtic were not carving out many openings themselves and their slender lead proved fragile when Johnson struck in off the post after the Ladbrokes Premiership champions failed to deal with a long ball.
“It felt like a win,” the striker told Motherwell’s YouTube channel.
“We always said it might be scrappy and we put them under pressure in the second half and they started kicking it out a bit.
“I think we got them a bit rattled. We just said stay in the game, keep it 1-0 and then when we get a chance, just take it. And I took it.
“I had nothing to aim for really, I literally had to smash it across goal and find the bottom corner. I found the post and gave (Craig) Gordon no chance.”
Johnson, whose team face Hearts at Tynecastle on Sunday, added: “To put the Livingston defeat right and come back and get a point against Celtic when many would have thought we wouldn’t get any, it’s something to build from and take it into the next five or six games.”
