Frank Lampard finally made his return to Chelsea on Thursday morning with the club announcing him as their new manager after weeks of speculation.
Five years after leaving Chelsea and just one year into his managerial career, Lampard has become the Blues new boss after Maurizio Sarri moved back to Italy.
The club's all-time top scorer will be itching to get ready for the new season, which is just 38 days away for the Blues, but he's got a lot to do before then.
We've put together a list of seven things that the former midfielder needs to do to hit the ground running at Stamford Bridge:
1. Get returning loanees back in the squad and play academy players
Chelsea have one of the best academies in the country, winning the FA Youth Cup six of the last eight years, but not many have made it into the first team and most end up going on loan for endless seasons.
With a transfer ban and Ruben Loftus-Cheek and Callum Hudson-Odoi injured it's the perfect time to reintroduce some of those who have been on loan.

In defence Lampard could use Fikayo Tomori who he had on loan at Derby whilst Reece James impressed at Wigan.
Midfielder Tiémoué Bakayoko will return from AC Milan but it's another Derby loanee Mason Mount who is most likely to get in the side and in attack Lampard could see Michy Batshuayi or Alvaro Morata return but Tammy Abraham might be the man to fill the void never filled since Diego Costa left.
2. Play N'Golo Kante in his best position
When Lampard gets to his tactics board and tries to wipe it clear he'll probably find Jorginho's name inked in with permanent marker but it's time to get rid of Sarri's tactics.
N'Golo Kante won the Premier League back-to-back in defensive midfield and won the PFA Player of the Year award with the Blues in that position.

Last season Sarri played him further forward and whilst it wasn't a complete disaster it certainly didn't help get the best out of the Frenchman, easily the team's best midfielder.
3. Let Kepa, and the rest of the team, know who the boss is early
How Sarri actually recovered from Kepa's insubordination at the Carabao Cup final is quite astonishing in itself but the new manager can't afford anything similar on his watch.
The 41-year-old will be keen to make sure the goalkeeper, and anyone else, knows who the boss is and how he wants to play is the best way.
4. Give Christian Pulisic time to make his mark
In January Chelsea spent £58 million on Christian Pulisic, potentially expecting their transfer ban from FIFA, letting him stay at Borussia Dortmund for the rest of the season.

The American is an exciting prospect, and scored twice in the Gold Cup on Wednesday night, but at 20 and starting in a new league he's likely to make mistakes.
Lampard and the Chelsea crowd must allow him to make those mistakes and get up to speed, he's very talented and could make a huge mark on the Premier League for many years.
5. Don't lose to Manchester United on the opening weekend
Jose Mourinho's first official game in charge of Chelsea was against Manchester United, so was Avram Grant's when he took over from the Special One, now Lampard will have the same.
The first Sunday of the season sees Chelsea travel to Old Trafford. Stopping Ole Gunnar Solskjaer's team from picking up points would be a great start to Lampard's start and instantly put a dampener on one of their rivals for the top four.
6. Beat Liverpool in the UEFA Super Cup
Nothing could be a bigger statement early in his time back at Stamford Bridge than beating Champions League winners Liverpool in the European curtain opener.
Liverpool will be hoping for another title push and beating the Premier League runners up would be great for confidence.
7. Have a chat with Roman about what's going on
The West London club's owner Roman Abramovich didn't come to watch a single game last season, after losing his visa last year, and there's been rumours the Russian won't invest a much in the club.
Lampard could do with finding out if they'll ever be a new stadium, how much he might have to spend next summer and if Abramovich is considering selling.
As well as all that the former England captain should obviously keep an eye on vacancies at other clubs, after all he's no idea how long he'll last at Chelsea based on the club's record for sackings.
