"Them showing their support by coming to the airport like they did and everywhere we go really buzzes us up a little bit and we have some energy going into this week now.
"It's been really good. The locals have made us feel really welcome and it's going to be a good experience so I'm looking forward to it all.

"Jack Hughes and Joe Philbin were here last year with the England Knights and they said the atmosphere was great.
"I'm looking forward to that and I'm sure there'll be a lot of people watching us at training as well."
