Palermo president Maurizio Zamparini has slapped a €50million (£36m) price tag on Paulo Dybala, telling Paris Saint-Germain they will have to spend big to sign the 'new Lionel Messi'. A bidding war is set to break out over Dybala, who is being tracked by Manchester United, Chelsea, Arsenal, Inter Milan, Juventus and PSG. Roberto Mancini was spotted at the Stadio Ennio Tardini on Sunday, when Palermo lost 1-0 against Parma, and the Inter manager was understood to be there to watch Dybala. Palermo president Maurizio Zamparini has slapped a €50million (£36m) price tag on Paulo Dybala . Dybala is wanted by Manchester United, Chelsea, Arsenal, Inter Milan, Juventus and Paris Saint-Germain . Inter Milan manager Roberto Mancini watched the Serie A match between Parma and  Palermo on Sunday . Yet the former Manchester City manager's fiercest competition would be Ligue 1 champions PSG, with Palermo determined to cash in. 'I'm in contact with the player's agent and with PSG president Nasser Al-Khelaifi,' Zamparini told Telefoot. 'For PSG, he would be a good investment for the future. 'For me, he is the new Messi. Today, how much would you pay for Barcelona's Argentine? €200m (£143m)? €300m (£215m)? And even at that price, would he be sold? 'Messi is worth an entire team and Dybala is this kind of player. I want €40m (£29m) for him but I asked Nasser for €50m (£36m). 'The boy's agents have already travelled to Paris to talk to the club but Dybala has some doubts because there are already great players there.' Dybala would more likely be guaranteed a first-team place in Italy rather than France, but could be sold to the Paris club if they are prepared to meet Zamparini's demands.
