The free-scoring exploits of Bas Dost, Sebastien Haller and Lionel Messi dominate's latest stats review, which also features an exciting Paraguayan youngster and Paris Saint-Germain's impressive home record.

5000 league goals was the milestone reached by Ajax on Sunday in their 4-2 win over Twente. But while the Amsterdam giants are the first team from the Netherlands to scale this impressive landmark, it was a player at another Eredivisie club who grabbed most of the headlines. Sebastien Haller, after all, scored four times in Utrecht's 6-1 win over Dordrecht, becoming the first Frenchman to achieve this feat in the Dutch top flight. He also became his club's first hat-trick scorer since Dries Mertens in May 2011 and the first to find the net four times since Igor Gluscevic in October 2000. In a remarkable coincidence, given events in the Bundesliga over the weekend, the last player before Haller to have scored four in a single Eredivisie match was a certain Bas Dost (more of whom later). For Utrecht, meanwhile, this was their most productive match in front of goal since a memorable 6-4 win over Ajax in 2011.

70 days after blowing out the candles on his 16th birthday cake, Sergio Diaz made a scoring start to his latest Paraguayan top-flight campaign. The striking prodigy, who exploded on to the scene last year and has just returned from playing - and scoring - in the South American U-20 Championship, struck the second goal in Cerro Porteno's 3-0 win over Sportivo Luqueno on Saturday. In doing so, he again became the youngest goalscorer in the world's top flights over the past week. As for the oldest, that honour belongs to Milton Nunez of Guatemala's Universidad San Carlos, a man who at 42 years and 108 days old is Diaz's senior by over 26 years.

31 Barcelona hat-tricks was the landmark reached by Lionel Messi on Sunday, taking him level with Telmo Zarra's record for a Spanish club. The Argentina icon's latest treble, in Barça's 5-0 win over Levante, took him three clear of Alfredo di Stefano (28) and established a gap of four between himself and Cristiano Ronaldo. Messi equalled this latest record in his 300th Liga appearance for the Catalans and, with five hat-tricks in 2014/15, this is already his most treble-filled season besides 2011/12, when he scored 12. His contribution also helped Barça rack up an 11th successive win in all competitions, the first time they have enjoyed such a run since Pep Guardiola's first season in charge.

8 years, three months and 33 matches have now passed since Paris Saint-Germain were last beaten at home in Europe - the longest active streak of any team. The French champions extended that run last night by drawing 1-1 with Chelsea, a match in which Edinson Cavani scored his 15th UEFA Champions League goal and his sixth of this season, a new personal best. In the evening's other match, Shakhtar Donetsk played out a goalless stalemate with Bayern Munich - the Germans' first 0-0 draw in the Champions League since September 2009. Bayern midfielder Xabi Alonso was making his 100th appearance in the competition but it was not to be a night to savour. Alonso was booked in the first half, collecting his 29th caution in the Champions League to move into second in the all-time list, ahead of Gennaro Gattuso (28) and second only to Paul Scholes (36). And red was to follow yellow, with the midfielder earning his second Champions League dismissal and becoming the first player to be sent off in his 100th appearance in the competition.

4 goals were scored by Bas Dost in Wolfsburg's thrilling 5-4 win over Bayer Leverkusen on Saturday, establishing him as the first-ever Dutchman to achieve this feat in the Bundesliga. The former Heerenveen striker, who scored with every one of his shots on goal, also became just the second player in Wolfsburg's history - Martin Petrov having been the first - to claim such an impressive haul. Dost was not the only in-form forward on show in the match, with Son Heung-Min notching a hat-trick for Leverkusen. The South Korean duly became the first Bundesliga player in 11 years - since Marek Mintal for Nurnberg against Hamburg - to score a treble and still end up on the losing side. This was also the first game in a decade with two hat-trick scorers on opposing sides. It was a weekend of goals galore in Germany, with Bayern Munich also rewriting records in an 8-0 thrashing of Hamburg. It was HSV's heaviest-ever defeat in the Bundesliga, a history encompassing 1751 matches, and left them having conceded 31 times against Bayern in the sides' last five meetings. For the reigning champions, meanwhile, this was their biggest win in over three decades - since a 9-0 demolition of Kickers Offenbach in 1984.
