Partick Thistle manager Alan Archibald could not hide his surprise after his side were awarded their first penalty in 18 months.

Sean Welsh's successful spot kick could not prevent Thistle going down 2-1 at home to Premiership leaders Celtic.

"Shocked, stunned," was Archibald's reaction. "The decisions in the first half, they went the other way.

"We got two players booked, which was ridiculous, so I was very surprised to see the penalty."

Thistle's previous penalty came 69 games ago when Kris Doolan missed the spot-kick in a 3-1 win over Inverness Caledonian Thistle in September 2014.

This time, referee Stephen Finnie blew the whistle in the 84th minute after Celtic defender Erik Sviatchenko tugged at Steven Lawless.

However, Celtic were already ahead through goals from Leigh Griffiths, shortly before half-time, then Callum McGregor not long after the restart.

"We were in the game in the first half and we had a couple of half chances, but we lost a terrible goal at a terrible time," added Archibald, whose side are eighth in the table.

"It came at a throw-in, which was very disappointing.

"Once they got their goal, we allowed them to play and we sat off and you can't do that with Celtic.

"We need to get rid of the defensive lapses and take some points."
