England defence coach John Mitchell knows the enemy a little bit better than most heading into this weekend's Six Nations clash with Wales.
After all, he and Wales coach Warren Gatland used to be flatmates.
The two European nations will clash this weekend but there will be a distinct Kiwi flavour in the mix with Mitchell and Gatland dueling in a battle of wits.
England will take on Wales at 4.45am this Sunday.
In other Six Nations matches, France will face Scotland at 2.15am Sunday while Italy will meet Ireland at 3am next Monday.
