GLASGOW forwards coach Jon Humphreys has promised there will be no hangover from their European Champ-ions Cup disappointment when the side return to league action tomorrow.

The Warriors received a boost yesterday when Nick Grigg, the centre who made his Scotland debut in the summer and is back in Gregor Townsend’s squad for next month’s Tests, extended his Scotstoun stay to at least May 2020 after penning a new contract.

The team are building nicely domestically, having won six out of six in the Guinness PRO14 but after two defeats from two games in Europe, the Warriors need to get back to winning ways quickly.

“We started this season pretty well but there were certain parts we always felt needed improving,” said Humphreys.

“We came up against two really good teams in Europe and it’s made us understand what we need to get better at to be successful. We need to hold on to the ball a bit more, create more pressure, not allow teams to get as much into the game as they have. It’s something we’ve reviewed and hopefully is something we’ll start making progress in.

“We want to do that on the weekend. It’s great to get back into the league but we can’t afford any hangovers.”

Facing the Southern Kings should be one of Glasgow’s more straightforward games. They are yet to win since joining the PRO14 and they arrived in Scotland on Wednesday, leaving themselves little time to adjust from the Port Elizabeth summer to the Scottish autumn.

Despite that, Humphreys is not expecting too many players to be given time off, apart from those running into the protocol that orders the clubs to rest players after five consecutive games.

“It’s been a big learning curve for quite a few of those boys who haven’t played at that level,” Humphreys said of the European campaign. “We knew before there were elements of our game that needed improvement and that has refocused our attention.

“We don’t let whether we win or lose affect how we review the game. We’ve been tough on each other after games though you probably don’t understand the level [in Europe] until you play in it. It was a great learning experience.”

As for Grigg, he still can’t believe that what started off as a bit of a jolly – “a chance of a free trip to Scotland to play a little rugby” – has worked out so well. It has earned him a professional contract, a cap and, maybe, the chance to face his fellow New Zealanders. So, signing a contract extension was one of his easier decisions.

The Wellington-born centre came to play for Stirling County, but knew there was a chance to go further since Townsend, then Glasgow coach, had been instrumental in securing his invitation.

“A couple of years later, my goals and aspirations have hit the roof,” he said. “As long as I keep working hard I’m sure I can achieve them.”
