Celtic striker Leigh Griffiths is closing in on the 100-goal mark as he insists he has put his recurrent calf injury situation behind him.

The Scotland internationalist sought specialist advice in an attempt to ascertain the reason for the repeated calf problems which have blighted his career over the last two seasons.

The striker currently has 97 Celtic goals to his name and he has backed himself to hit the century before the curtain comes down on the current campaign.

“That is my aim,” said Griffiths. “I have no doubt that if I stay injury free I will get that 100 mark. It has been a long time coming but when I hit it, it will be a great achievement for myself.”

And the striker is itching to get back on the park after two-month absence.

“It has been long. It’s been depressing,” he told Celtic TV. “These calf injuries have been a nightmare since the manager came in but hopefully I have found the cause of it and it is finally fixed.

“It is disappointing when you are missing first-team matches but the most important thing is you need to get back fit and make sure it doesn’t happen again. Hopefully that’s the end of the problems.

“The quicker I get back to first-team action, the better. I have been working really hard to get back to full fitness and hopefully that is me raring to go.

“We have big, important games coming up. The quicker we can get the points on the board to secure the title the better then everyone can have fun.”

Griffiths was pictured celebrating among the Celtic fans earlier this month as ten-man Celtic came from behind to beat Rangers. The player looked to be at home as he took centre stage with the celebrations but he has admitted that he would rather have been on the pitch.

“Of course it was enjoyable to watch the boys winning and move closer to the title,” he said. “But it was frustrating not to be involved in the celebrations on the park but I had a good time in the stands with the rest of the fans.”

Meanwhile, the striker is also looking to play a part in Alex McLeish’s Scotland squad and admitted that he still gets a kick out of seeing his free-kicks against England back.

“One of them is my pinned tweet on twitter so it is always nice to go back and refresh your memory,” smiled the forward. “It is something I will always remember but you need to look forward. We have important games next season for the national side and hopefully I can be a part of that. “That is another part of the process to get back involved in that squad. I was disappointed not to be involved with that one but first and foremost I had to get fit for Celtic so I can’t get too downhearted about it. We have big important games before the break and hopefully I will be involved in that.”

Celtic confirmed this week that we will host the Republic of Ireland in May for Scott Brown’s testimonial. And Griffiths believes it is a fitting accolade for the current Celtic captain.

“It is a phenomenal achievement to be here for 10 years,” he said. “He has done everything that he can at this club and it is only fitting that he gets a testimonial.

“He is a great leader on and off the park. He is a great lad and a close friend and it is nice to see him get the recognition he deserves.”
