Championship play-off final: QPR and Derby in numbers

QPR boss Harry Redknapp believes Derby County are favourites to win the Championship play-off final

Queens Park Rangers and Derby County will face each other at Wembley on Saturday in what is billed as the most lucrative game in world football - the Championship play-off final.

As well as a place in the Premier League, promotion could be worth up to £120m to the victor.

BBC Sport looks at the numbers behind the play-offs and the two teams competing in the final.

Play-offs in numbers:

36% - The teams that finish third in the Championship have the highest percentage of securing promotion via the play-offs.

That is good news for Derby, who finished third, but the bad news for QPR is that the team finishing in fourth has gone on to win the play-offs in just four out of the last 25 finals (16%), the least of any side finishing in the play-off places.

1998 - The last time a team finishing in fourth place won the play-off final. In two of the last three finals, the team finishing third has secured promotion to the Premier League.

Four - Derby have won four of their previous five play-off games. They also won the last final they appeared in, beating West Brom 1-0 in 2007. QPR, who edged Wigan over two legs in the semi-final, have never featured in a play-off final at this level before.

Queens Park Rangers in numbers

£80m - The amount, according to the Sports Business Group at Deloitte, promotion back to the Premier League could be worth to QPR.

£68m - The club's wage bill for the 2012-13 season as Rangers unsuccessfully battled against relegation from the Premier League. When they were promoted to the top flight in 2010-11, their wage bill was £30m.

£65.4m - The amount QPR lost for the year to 31 May 2013. That loss was £13.4m more than 2013-14 Premier League champions Manchester City lost in the same period and £57.8m more than Burnley, who were promoted automatically to the top flight.

Clubs losing more than the £8m set under Financial Fair Play (FFP) rules in 2013-14 are subject to sanctions.

Charlie Austin finished the season as QPR's top scorer with 20 goals

£177.1m - The club's total debt for the year up to May 2013, which was up from £91.4m in the 2012 accounts.

4,264 - The total amount of appearances in the Premier League made by the 27 QPR players who have previously played in the top flight. For Derby, that figure is just 170.

455 - QPR's Aaron Hughes has played the most top-flight games while John Eustace leads the way for Derby with 49 Premier League appearances.

25 - The number of signings Harry Redknapp has made, either permanently or on loan, since he became manager in November 2012. Since last summer, 19 players have been brought in, including five on the final day of the January transfer window.

18 - The number of full international players in the QPR squad. Derby have six.

What they say:

"I think Derby are the favourites. They have been on a great run and Steve has done a fantastic job with them. They are a young side, full of energy. It's got all the ingredients of being a good match-up." QPR boss Harry Redknapp.

"Harry Redknapp would always ask for more and it was never one more player but two more. I would tease him and say 'when will you stop pestering me?' His talent was getting players, motivating different players in different ways and knowing what the team needed." Former Portsmouth chairman Milan Mandaric.

"What you get for getting through is massive; not just for me and the players but for the fans, for next season, for the manager and the staff and everyone involved with QPR. At the end of the day we all want to play in the Premier League." QPR defender Danny Simpson.

Derby in numbers

£120m - The amount promotion to the Premier League could be worth to Derby, according to Deloitte.

£10.5m -The club's wage bill, for players and administrative staff, for the year ending 30 June 2013.

£7.1m - The amount Derby lost in the year up to June 2013. That was down on the 2012 losses of £7.9m.

24,933 - Derby's average attendance in the Championship in 2013-14. That is 8,278 higher than QPR's average of 16,655.

£750,000 - The biggest transfer fee paid by Derby since last summer as striker Johnny Russell joined from Dundee United.

Steve McClaren returns to Wembley for the first time since 2007, when he was England manager as the Three Lions lost 3-2 to Croatia to miss out on qualification to Euro 2008, costing McClaren his job

27 - The number of players used by Derby County this season, 13 of those making 30 appearances or more.

12 - The amount of players Derby have signed, either on loan or permanently, since last July.

Six - Derby last played in the Premier League back in the 2008-09 campaign, six years ago.

One - The number of wins Derby managed during that record-breaking season - a 1-0 victory over Newcastle. They were relegated in March with just 11 points, the lowest-ever total in Premier League history.

What they say:

"I'm looking forward to it - we all are. We're a bit like the swan on the river - cool and calm on the surface but underneath paddling like hell." Derby manager Steve McClaren.

"His research is second to none. He is always looking for the next thing, looking to get better and challenge himself - even though he has been in the game so long. He still wants to learn." Jimmy Floyd Hasselbaink, who played under McClaren at Middlesbrough.

"We have the basis of a Premier League squad, I don't think we need to make hasty changes. I think we have a super squad and we will look at that as things go on." Derby chief executive Sam Rush.
