Partick Thistle: Early goal killed us, says manager Alan Archibald

Partick Thistle manager Alan Archibald felt they handed Celtic the initiative too easily as they lost 5-1 at Firhill .

Anthony Stokes scored a double while Liam Henderson, Stefan Johansen and Kris Commons also hit the net.

Christie Elliot grabbed a consolation as Neil Lennon's side clinched the Scottish Premiership title.

"We can't give them a gift," Archibald told BBC Radio Scotland. "We spoke about it before the game, you can't give them a good start."

Celtic scored minutes into the game through Stokes and did the same again at the beginning of the second-half.

"We let them in the game," he said. "We let Anthony Stokes get a header from six yards out after two minutes and I think it killed us.

Probably the worst thing that happened to us was getting the goal to make it 3-1

"It took the wind out of our sails. It took us a while to get back in the game.

"We got back in, started to play a wee bit for 20 minutes of the first half and then we give them a goal at the start of the second half and it kills you.

"They went 2-0 up and then they started to pick us off."

Thistle remain in 10th position, two points ahead of St Mirren in the relegation play-off place.

Archibald is confident his men can get back to winning ways if they cut out the mistakes that allowed Celtic to rack up the goals.

"Probably the worst thing that happened to us was getting the goal to make it 3-1," he said.

"Then, for some reason, we started to go try and chase the game and left spaces in behind. They had pace to burn at that point.

"Anything we took tonight was a bonus, no doubt about that. And our fight starts now on Saturday against St Johnstone.

"We said to the boys when the game goes to 3-1 'don't make mistakes, don't let them mistakes creep into your game'.

"As long as we don't do that on Saturday, we'll be fine."
