On Thursday morning, England manager Roy Hodgson included Drinkwater in his squad for the two friendly internationals with Germany and the Netherlands as he tries to take advantage of the last chance to assess players before Euro 2016.
It had been suggested that Drinkwater was in direct competition with West Ham United's Mark Noble for a place in the squad, with the Foxes player being given the nod and he is expected to make his Three Lions bow in one of the games.
Moments before the squad announcement, Pearce, who made 78 appearances for England during his playing career, claimed that Drinkwater should automatically come into the reckoning having played a significant part in Leicester's rise to the top of the Premier League table.
Pearce said: "Drinkwater has had a wonderful season and he has been a big part of their success.
"If you are sat at the top of the league and you have played near enough every game in the centre of midfield, you have to be taken seriously."
Drinkwater, who represented England at Under-18 and Under-19 level, has scored two goals in 30 appearances in all competitions this season.
He spent his youth career at Manchester United but failed to play in a senior match at Old Trafford.
