Winning the club's first Eredivisie title would give McClaren hero status in Enschede, a city in eastern Netherlands perhaps best known as the home of Grolsch beer.
Babel admitted it was a tough decision to leave Ajax, where he made his debut aged 17 in 2004 and scored five goals in 27 Eredivisie matches last season.
Nonetheless, many Twente fans were initially suspicious, but in his first season, McClaren led the Tukkers to the domestic cup final and second place in the Eredivisie, earning plaudits for playing the 'Dutch way' in a 4-3-3 formation.
