Jan Kromkamp insists he has no hard feelings over his unsuccessful spell at Liverpool but is ready to pile on the misery for Rafael Benitez's men on Tuesday night.
The full-back joined PSV Eindhoven on transfer deadline day after surviving less than a year at Anfield and is set for a quick reunion with his former team-mates in Tuesday night's Champions League Group C opener at the Philips Stadion.
The Reds arrived in Holland today on the back of their worst Merseyside derby defeat in 42 years, 3-0 to Everton, and Holland international Kromkamp believes PSV can rub salt into an open wound.
'Liverpool are a quality side,' he said. 'But I feel you should not even start a game when you lack the confidence to earn a victory yourself. So yes, I think we can beat Liverpool.'
However, the 26-year-old has warned his team-mates to expect a backlash from the five-time European champions, admitting the Reds are a different proposition in continental combat.
'The Champions League is a completely different kind of competition,' he said.
'A team will only be eager to return to winning ways once they have slipped to defeat.'
Kromkamp started only seven Barclays Premiership games for Liverpool following his January move.
While he admitted to a degree of frustration, the defender had nothing but kind words for his former employers, with whom he won the FA Cup last season.
'I found it hard to find my rhythm when I was not given much playing time,' he added on PSV's official website.
'I need to play games to get in shape. I loved my spell with Liverpool and I will always cherish fond memories of the FA Cup final.
'But now I am delighted to be here, as PSV are a great club.'
Manager Ronald Koeman has dismissed Liverpool's derby debacle as irrelevant to tomorrow's encounter but the former Benfica boss is ready to upset the odds again after ending their reign as European champions last season.
'Liverpool will field more or less the same players,' he said. 'They have made some changes, but not that many.
'I expect they will play their familiar game. They still have the same coach and their game-plan will not have changed much.
'We [Benfica] met them twice last season.
'I have learnt from the double leg that they are hard to beat. That's why I think the result of the Everton game does not mean that much.'
He added: 'I take it for granted Dirk Kuyt will start.'
On his own team selection, Koeman is pondering whether to give a debut to recent signing Patrick Kluivert, who scored against the Reds in previous spells at Barcelona and Newcastle.
'We will decide tomorrow whether he will be called up,' Koeman said. 'I feel it's up to the player himself to a great extent as well.
'I have my own ideas and I will discuss them with Patrick and together we will take the decision. But it is doubtful if he starts on the bench tomorrow night or Sunday, when we take on Feyenoord.'
PSV will be without veteran midfielder Phillip Cocu through suspension but Koeman has backed the rest of his players to make up for the 35-year-old's absence.
'We realise only too well we will miss his ability to change things tactically on the pitch,' he said.
'But that does not imply we will field a far weaker side.'
