the Premier League, before finally returning for the 2020–21 season, under the guidance of Marcelo Bielsa. A more extreme example of the struggles associated with adapting to relegation would be that of previous Premier League champions Blackburn Rovers, who were relegated from the top flight on 7 May 2012, and struggled to stay in the EFL Championship over the next five seasons before finally dropping to League One on 7 May 2017, earning the dubious distinction of being the only former Premier League champions to play at that level. This was in spite of Rovers initially spending substantial amounts of money following their relegation from the Premier League, breaking their transfer record to land Jordan Rhodes for £8 million in the 2012–13 season. Rovers would proceed to become a cost-cutting club, due to the exhaustion of their parachute payments across multiple seasons, large amounts of debts beginning to surface reportedly within the region of £100 million, and a lack of investment from their owners Venkys, culminating in their relegation to League One. Another notable example of a former Premier League club that has struggled both financially and competitively, despite being in receipt of parachute payments, would be that of Bolton Wanderers. Having spent beyond their means throughout the club's 11-year tenure in the top flight, Bolton steadily declined with regards to league position in the years following their Premier League relegation in 2012, eventually dropping down to League One in 2016. That season, the club's perilous financial situation necessitated the sale of their Euxton training ground and a car park in use by the club. The club had amassed debts of £186 million to their previous owner Eddie Davies, of which £171 million was eventually written off in order to assist with selling the club. Bolton Wanderers and its parent company Sports Shield BWFC, have faced multiple winding up petitions from HM Revenue and Customs for unpaid loan debts to various external businesses amounting to approximately £30 million; including an unpaid £5 million loan to BluMarble, a finance company that had provided funds to facilitate a takeover deal for the club in March 2017, and an overdue loan debt of £5.5 million to Prescot Business Park Ltd. Bolton's most recent financial accounts have produced forecasts that predict an annual loss of roughly £11 million, with the club judged "unable to meet ongoing costs".
