JON WELSH is celebrating become Glasgow Warriors latest centurion.

And the 28 year-old is ready to give Munster a battle they won't forget this weekend as they come to Scotstoun in a clash of the Guinness PRO12 titans.

The Irish cracks are currently top of the standings Warriors joint-second just a point behind.

Victory in the confrontation would see Gregor Townsend's men leapfrog their visitors going into Christmas.

And Welsh, who recently racked up his 100th appearance in a Glasgow jersey, is ready for the challenge.

He said: "It's a massive game.

"They are top of the league and we're joint second just now, so we prepare for it the same was as any other game, and that is to win.

"Those two games we lost [to Toulouse in the European Champions Cup] were narrow defeats, but we go back to the drawing board, see where we went wrong and where we need to improve on, and we take that into training and forward into the game."

The last time Munster came to town was back on May 16 in the Pro12 semi-final.

It would turn out to be one of the most historic days in Glasgow's history as they triumphed 16-15 to advance into the final against Leinster.

Welsh has fond recollections of that day, and said: "I remember at the full-time whistle I was sitting down with the rest of the boys who had been substituted.

"Everyone was just roaring and cheering at the one time. I said to Chris Cusiter that it was almost just like euphoria.

"You just didn't really know where you were for a minute. It was a great feeling to get into the final and we look to build on that and take it further this year."

Of course, become a Warriors centurion is something which should be celebrated in its own right.

Scotland international Welsh now is part of an illustrious group to have reached the landmark, and it's clear the significance is not lost on him.

He told WarriorsHQ: "It was a massive honour. It's a privilege every time you pull on a Glasgow jersey but to get to 100 is great. I just can't quite believe it, to be honest.

"Some of the guys who have reached that before me are great players. Guys like Graeme Morrison, John Barclay, Al Kellock and Murray Low. Guys who have been massive servants to the club. To become a part of that is really humbling.

"This is the start of my seventh season now. I remember when I first came in and everything was so different.

"From where we trained, the personnel with my team-mates and friends I've made throughout the years, to where we are now.

"We have been having a good run in Europe and it's great to see the club grow each year from strength to strength."

He added: "The other week Ryan Grant turned round and said to me that the saddest thing about playing at the weekend was that he was the oldest guy on the pitch. When he said that to me I couldn't believe it.

"That's professional rugby for you, though. You are enjoying yourself so much that you don't see the time going by."
