It's been another big week in world football, with some big completed moves and some huge offers being lodged. In today's briefing, we take you through the nine biggest stories of the last five days, which includes a 19-year-old talent heading to an Italian giant, Barcelona's bid to bring back a former star to the Camp Nou and an England international making a switch to La Liga.

Matthijs De Ligt has long been linked with a move away from Ajax this summer after a fantastic season in which he led the Eredivisie side to the Champions League semi-finals and impressed whilst playing for the Dutch national side. And this week, his next destination was confirmed - the 19-year-old has completed his move to Serie A side Juventus. The Old Lady paid £67.8m for the centre-back, who has signed a five-year deal with his new club and will earn a basic £14.5m a season.

The English player abroad is not a path well trodden in recent years, but Jadon Sancho's performances at Borussia Dortmund appear to have inspired others to try their luck in another European league. The latest is Kieran Trippier, who has completed a move to Atletico Madrid from Tottenham Hotspur. Los Rojiblancos have paid £20m for the England international, who has signed a three-year deal to stay at the Wanda Metropolitano.

Marko Arnautovic's departure for Shanghai SIPG has increased West Ham's need to bring in a new striker this summer. Fortunately for the Hammers, they do not need to look any further. The Irons have signed Sebastien Haller from Eintracht Frankfurt for a fee of £45m, with the 25-year-old signing a five-year deal with the London outfit. The former Utrecht striker contributed to 32 goals in all competitions last season for the Bundesliga side as they reached the Europa League semi-finals.

Borussia Dortmund have had a busy summer, having already brought in five new faces. The biggest of those was the capture of Mats Hummels, who BVB re-signed from Bayern Munich. Of course, this means that some players will need to be moved on to make space for the fresh recruits. One of those who has departed the Signal-Iduna Park is Abdou Diallo, who has signed for PSG. The Ligue 1 champions have paid a fee of £29m to the German outfit for the centre-back, with the 23-year-old putting pen to paper on a five-year contract.

As a professional footballer, it should be obvious that using your position and inside information to make bets is a no-go. Not for Daniel Sturridge though, it appears. On Thursday, the former Liverpool striker was banned from all footballing activities until July 31st. He was found guilty on two of 11 counts for which he was charged -  he had instructed his brother to bet on a possible move Sevilla, and then given him insider information. The 29-year-old will also have to pay a fine of £75,000.

Neymar has not had the best of times at PSG recently, and is reportedly looking for a move this summer. A return to Barcelona seems most likely, and now there has has been an update in the saga that could run until the end of the summer. It is being said that the Catalan club have made an offer of £90m offer plus two players for the Brazil ace. The Ligue 1 outfit have apparently been given the choice of taking two of Philippe Coutinho, Ousmane Dembele, Ivan Rakitic, Nelson Semedo, Malcom and Samuel Umtiti. However, it is understood that the Qatar-owned side want over £200m for the 27-year-old.

Newcastle had been previously linked with a whole host of names as they looked to replace Rafa Benitez, who left his role as the club's manager last month. Earlier this week, though, they finally filled the vacant position. The new Toon boss is none other than Steve Bruce, the former Sunderland manager. The 58-year-old has signed an initial three-year deal with the North-East side. He said upon his appointment, "I’m delighted and incredibly proud to be appointed as head coach of Newcastle United. This is my boyhood club and it was my dad’s club, so this is a very special moment for me and my family."

RB Leipzig already have a young squad, and now they have added another up-and-coming talent to their ranks. It has been confirmed by the club themselves that they have signed Christopher Nkunku from PSG on a five-year contract. Die Roten Bullen have reportedly paid €13m (£11.7m) for the France U21 international, who scored 11 goals in 78 games from the centre of the midfield for the Ligue 1 side.

It was always clear that Salomon Rondon would no longer be a West Brom player at the end of the current transfer window. Finally, his new club has been revealed. The Venezuela international has joined former Newcastle manager Rafa Benitez at Chinese Super League side Dalian Yifang. The 29-year-old has moved to China for an undisclosed fee, the Baggies confirmed on their official website. It brings an end to a four-year spell at the Hawthorns for the former Zenit St Petersburg striker.
