Why is Chelsea vs Nottingham Forest being played at 3pm on a Monday?

The Blues come into the affair having failed to take a point from any of their last five Premier League matches, a run of form which has seen them tumble down the table.
Under the interim leadership of Calum McFarlane, though, they will hope to breathe fresh life into their campaign.

Last time out, McFarlane won the first match of this, his second spell as Chelsea’s interim head coach this year, edging Leeds in the FA Cup semi-final.

Why does Chelsea vs Nottingham Forest kick off at 3pm on a Monday?
Chelsea and Nottingham Forest have been assigned an abnormal kick-off time because the match had to be rescheduled.
It had originally been set to take place on Saturday, May 2, but such a kick-off time would have seen the match take place less than 48 hours after Forest’s Europa League semi-final first-leg against Aston Villa.
Sunday afternoon had been the go-to alternative in such cases earlier this season, but with Monday being a Bank holiday, the Premier League was allowed more flexibility. to maximise viewership
Thus, the match was bumped to Monday afternoon, making up a double feature with Everton and Manchester City kicking off at 8pm BST.
Forest will return to European action on Thursday in the second leg of their Europa League semi-final, where they lead Villa 1-0 on aggregate.
Aston Villa hosted Tottenham in the Premier League on Sunday afternoon.
