of just winning away at Westerlo. Westerlo On 16 November 2015, Peeters was appointed head coach of Westerlo. He succeeded Harm van Veldhoven who was fired the day before. Peeters' main goal in the 2015–16 season was avoiding relegation, something that he succeeded in on 13 March 2016 by winning 1–0 against Waasland Beveren. OH Leuven had lost their home game against Club Brugge on the same day, making them the relegated club of that season. On 13 September 2016, Peeters was dismissed as head coach of Westerlo. Return to Westerlo In December 2017, Peeters returned as head coach of Westerlo, who had meanwhile been relegated to the First Division B. His first match in charge was a 1–0 win over OH Leuven on 9 December 2017. Westerlo's last victory dated from 30 September that year, after which the club only gained three points out of 30 under Vedran Pelić, who later stayed on as assistant to Peeters, together with Eric Reenaers. Westerlo finished penultimate in the regular season that season. In the play-offs, however, they remained undefeated, after which Westerlo moved up to sixth place. In November 2018, Peeters was linked to a return to Waasland-Beveren, but in the end he stayed with Westerlo after the club offered him a contract extension until 2023.

In the 2019–20 season, Westerlo competed for the first period championship, but in the end they finished three points below OH Leuven. The second period championship was also a tight affair – with three match days to go, Westerlo were in the lead together with OH Leuven, Beerschot and Virton –, but with two matchdays to go, Westerlo had their fate in their own hands: with six out of six points they had enough for a final spot in the play-offs. However, on the final matchday, Westerlo lost 3–1 to Union SG, so that Beerschot, not Westerlo, had the opportunity to promoted. Westerlo therefore no longer had a chance to promote, despite the fact that they had achieved the most points in the final ranking. Westerlo also made a run at promotion in the 2020–21 season, especially considering that the period championships were abolished that season and therefore only the champion
