Celtic striker Leigh Griffiths is happy to keep proving his doubters wrong after coming off the bench to score Celtic’s Europa League winner against Rosenberg on Thursday night.

The 28-year-old has suffered the double disappointment of losing both his Celtic and Scotland starting berth in recent times and he was again among the substitutes for the Bhoys Group B encounter in Europe’s second-tier competition.

Manager Brendan Rodgers called on his services with 14 minutes to go and the former Wolves hit-man delivered the goods in the 87th minute, heading past Andre Hansen to make it a winning start at Celtic Park.

And, having bagged 211 goals 415 appearances in all competitions for five different clubs, the Leith-born ace was happy to prove those who feel he is not up to the mark wrong once again. “I’ve done it for years,” he said.

“I don’t know why people keep doubting me and say I can’t score goals in the big occasion.

“I’ve done it in the Champions League, the Europa League, the League Cup, the Scottish Cup and the league.

“There are still people out there doubting me and saying that I can’t do this and that. But I keep shutting people up.”

Griffiths is yet to score a league goal for the Hoops this term but will get another chance as Celtic travel to Kilmarnock for a lunchtime kick-off on Sunday.

They are priced at 1.44 to take all the points, with Killie on offer at 8.00 and the draw 4.50. Celtic are 51.00 to win the Europa League, with Chelsea the 5.50 favourites.
