The 25-year-old admits he owes a debt of gratitude to Potters boss Tony Pulis - who has helped inspire his rise from Manchester United's third team to England international - and will repay the faith shown by putting pen to paper on a long-term deal.
Red Devils boss Sir Alex Ferguson has been credited with an interest in re-signing Shawcross, after allowing him to leave Old Trafford permanently in 2008, but is facing competition from Spurs, with Andre Villas-Boas also keen on luring the centre-back to White Hart Lane.
"The main reason I want to stay is the gaffer," he said. "He's been great to me throughout my time here and made me captain at a young age.
"I've told him I want to stay here. I feel like he's improved me every year – and he got me into the England squad because that's been a goal of mine.
"It showed that a Stoke player can get into the England squad, because that's been an issue. But I've been in the last couple of squads now so that shows I'm playing well and I can get in there. Would I look to go, even if a top four club came in? No."
Shawcross was instrumental at the weekend again as he captained Stoke to a 1-0 victory over West Brom at The Hawthorns, lifting them to ninth in the Premier League table.
