EPISODE four of Welcome to Wrexham premiered on Disney+ today (May 17) and here's five things we learnt. 

The award-winning documentary covering the highs and lows of Wrexham AFC under the ownership of Ryan Reynolds and Rob McElhenney returned to screens earlier this month. 

The newest episode of the hit docu-series, labelled 'Risky Business' was released on Friday and here's five things we learnt:

1. Prank wars - Episode four starts with the battle of Ryan and Rob's birthday pranks. After Ryan's song for Rob's birthday, the Always Sunny star got the help of Chris Pratt to launch plans for the park in Wrexham.

2. Finances - Ryan and Rob's finances are examined in episode four, along with their dreams of becoming a Premier League club. Despite spending the required money to get out of the National League, there is a big disparity between the Reds owner's wealth and that of top Premier League sides. 

3. Revitalise - As part of Rob's plans to transform the old Hippodrome site, episode four also hints at revitalising other aspects of the town to bring it back to its former glory.

4. Vault33 - Episode four features a lot of the behind the scenes of Neil Roberts' new venture opening Vault33 in town. 

The new bar opened its doors earlier this month and has proved popular amongst locals and fans get to see just how the new development came about.

5. Business interests - During episode four, fans get to see a glimpse of the support offered by Rob and Ryan to the players for plans outside of football. 

Rob sits the players down and lets them know if there is anything they can do to help then they will, which later leads to Ollie Palmer and his Wrexham clothing brand. 

The players are obviously taking it on board, with Paul Mullin releasing a book and Jordan Davies' involvement in the Croes Howell.
