Instead, the Spurs pair slept under canvas together during England’s stint at a Marines boot camp.
Despite the ongoing battle for selection at Spurs, and the one that has just started at international level, Trippier, 26, says there is an unbreakable bond between the two.
He explained: “We are good mates and whoever plays, we are always there for each other.
“We always help each other and it will be no different here. I want to play and he wants to play but if he plays, I’ll help him. If I get picked, I know he will do the same for me.
“We have been playing with England since under-19s in the Euros so we have known each other for a long time and we always try and give credit to each other whoever plays.”
Trippier also represented England at under-21 level over six years’ ago so is understandably thrilled to finally make the progression to the seniors.
When the call came, though, it went first to Mauricio Pochettino while Spurs were in Hong Kong for their post-season match.
Trippier explained: “He called me in and said ‘I know what you did last night’.
“I thought I was in trouble even though I didn’t do anything. He scared me and brought in Hugo, the captain. I thought ‘did I do something last night? No I didn’t’.
“He then said – congratulations, you have been called into England. I was delighted for my mum and phoned my parents straight away as they have done a lot of hard work to get me where I am.”
Unfortunately, they didn’t ready him for life as a Marine.
“It was a great experience, mentally tough … but me and Walks put the tent up the wrong way round!”
