McClaren has impressed during his managerial spell in the Netherlands, helping Twente finish second in his first season.
And he is on course to win the title as the campaign reaches its climax.
"We missed an opportunity but we still have it in our own hands," he added ahead of Sunday's clash with Feyenoord.
"The reaction of the team is very important. We must now win the last two games and go for it."
Before succeeding Sven-Goran Eriksson as England head coach in 2006, McClaren guided Middlesbrough to League Cup glory in 2004 as well as to the final of the now defunct Uefa Cup in 2006 in Eindhoven where they were beaten 4-0 by Sevilla.
