Youssouf Mulumbu is delighted to have exacted 'revenge' on those who doubted him during his days at Paris St Germain.
The Congolese midfielder graduated through the youth ranks at the French giants, stepping up into the first-team fold in 2006.
He was, however, restricted to sporadic outings during his time at Parc des Princes, forcing him to eventually look elsewhere for games.
A loan spell at Amiens in 2007/08 allowed him to take in regular football, before West Brom came calling in February 2009.
The Baggies were suitably impressed by a short-term loan and snapped him up on a permanent basis at the end of the season.
During his two seasons with the Midlands-based club, Mulumbu has become a key figure in a side which currently occupies a mid-table standing in the Premier League.
The 24-year-old is pleased to have finally made his mark on the big stage, allowing him to prove a point to all the doubters who held him back during his early career.
Mulumbu told L'Equipe: "It was difficult to hear everyone but the coach and his assistant saying you should be playing. I still hold a grudge against Paul Le Guen.
"But I understand that the coach is under a lot of pressure in Paris and has to be wary of using young players.
"It is a shame because when you see Barcelona using six or seven players educated at the club, you think why not at PSG? They don't offer the same opportunities.
"When I was loaned to West Brom I almost didn't play [due to a thigh injury picked up before his first match] and I was scared about going back to PSG.
"Today my success can be considered revenge. I have shown that maybe people in Paris should have shown more faith in me."
