The 26-year-old, who enjoyed an impressive season with Spurs, has been included in the England squad by Gareth Southgate for the upcoming World Cup qualifier against Scotland.
Tripper said: "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."
