Speaking to the Daily Mail, Loovens has admitted that if he could turn back time he would want to return to 2009, and the injury he suffered whilst playing with Celtic.
The centre-back said: “If I could turn one thing back in my career, it would be to take time to heal it [the injury] properly the first time and so to be fit for the rest of the season. It happened while I was at Celtic.
“The manager wanted me to play – I can’t remember if it was Tony Mowbray or Neil Lennon - so I tried to force it and it went twice more. It was during the period when I was involved with the national team and we had the World Cup in South Africa coming up, which I missed because of it.”
Both Mowbray and Lennon were in charge that 2009/10 season, and Loovens' injury meant he missed the entire second half of the season.
It was Mowbray who asked him to play when he was not fully recovered, and then after some short reoccurrences of the injury in the early part of 2010, the now Wednesday captain missed the entirety of Lennon’s time in charge at the end of that campaign.
He was just making his way into the Netherlands international set-up at the same time as he suffered his injury, and the two caps he won were meant to be added to in the 2010 World Cup.
However, the injury he suffered meant that he missed all the pre-tournament warm up games, and as he had no football to his name at club level, Bert van Marwijk decided not to take him to the finals tournament.
Loovens did establish himself back in the Celtic side under Lennon the next season, before leaving in 2012 for Real Zaragoza. He stayed in Spain for one season, before linking up with the Owls in 2013.
The 31-year-old has now played over 50 games for the Championship club, but if he was not struck down with that injury in 2009, there is no knowing just how good Loovens could have become.
