For many football fans, September is the month that the football season really kicks into life.
Teams have found their feet and the tables begin to take shape, we take a look at 10 games you really don't want to miss...
1. Manchester United vs Everton
Wayne Rooney's first return to Old Trafford with Everton is sure to be a lively occasion although it is unlikely that he will get a bad reception from the home fans.
The Toffees don't have a bad recent record at Old Trafford, they won in 2013 and drew 4-4 in 2012, a game which cost United dearly in the title race. They were also seconds away from victory in April before a stoppage time penalty from Zlatan Ibrahimović earned the hosts a point.
2. Lazio vs AC Milan
Head coach Vincenzo Montella has made it clear that he is the man to bring the good times back to AC, who have endured some troubled times recently. They've made some big money signings over the summer including the arrival of Leonardo Bonucci from Juventus.
It's been a promising start to the new season with two wins from two but this will be a stern test against a Lazio side who have already beaten Juventus in the Supercoppa Italiana.
3. 1899 Hoffenheim vs Bayern Munich
Bayern Munich are the dominant force in German football. They've won the Bundesliga in each of the last five seasons and have won the league 27 times in total. Last season, they finished 15 points ahead of second place RB Leipzig, only losing two games all season.
One of those defeats though came away to Hoffenheim, who were the surprise package of the season, finishing 4th and earning a Champions League Play-Off Place for the first time in their history
4. Barcelona vs Espanyol
Despite being taken apart by Real Madrid in the Spanish Super Cup, Barcelona have won both opening La Liga matches and for now appear to be coping without the departed Neymar and injured Luis Suarez.
They welcome city rivals Espanyol to the Nou Camp boasting a hugely impressive record against them.
The match is expected to be more than just a game of football with sets of players and supporters expecting to pay tribute to those who died in the recent terror attack in the city.
5. Nice vs Monaco
3rd vs 1st from last season meet at the Allianz Riviera, a venue which still haunts England supporters. Despite only finishing two places apart from each other last season, Nice were 17 points behind Monaco, who finished with an amazing goal difference of +78.
Considering PSG's spending over the course of the summer, this game could go a long way in determining who finishes 2nd and clinches the last automatic Champions League spot.
6. Celtic vs PSG
A lot of stadiums claim to boost a famous atmosphere but there really is nothing like Celtic Park on a European night and the arrival of Europe's big spenders is sure to produce a spine-tingling atmosphere on the opening night of the Champions League.
Celtic have landed some big wins in Europe in the past, few better than that unbelievable performance against Barcelona in 2012. Given their struggles in Europe last season, knocking over PSG would be quite a statement for Brendan Rodgers.
7. Tottenham vs Borussia Dortmund
Will the Wembley curse strike again? It looked like Spurs had conquered their demons against Burnley before Chris Wood slotted a stoppage time equaliser.
After a bitterly disappointing group stage exit last season, Spurs have been given a very tough draw this time around, starting with the 2013 finalists Dortmund, who were beaten at Wembley by Bayern Munich in that final.
8. Sheffield Wednesday vs Sheffield United
After a six year gap, the Steel City Derby returns as Wednesday and United clash at Hillsborough. Their rivalry is widely regarded as one of the biggest in the country.
Wednesday have enjoyed the upper hand of this fixture in recent years with United not winning a Hillsborough derby since 2001.
9. Manchester United vs Burton Albion
You have may missed the 3rd Round Draw of the League Cup with it taking place in Asia at 4.15am UK time. It wasn't even shown on British TV, presumably so we couldn't see the EFL mess the draw up, again.
It has thrown up a repeat of a famous FA Cup tie from 2006 when Burton Albion, then a non-league club, drew 0-0 with Manchester United. It earned the Brewers a night out at Old Trafford in the replay where they beaten 5-0 by a United side that featured Cristiano Ronaldo.
10. West Ham vs Tottenham
For Tottenham fans, Arsenal is their big derby of the season but for West Ham, unless they draw Millwall in the Cup, this is the fixture they look forward to.
In a troubled first season at the London Stadium, West Ham's 1-0 win over Spurs in May, which virtually handed Chelsea the title, was a highlight. Slaven Bilic could desperately do with a repeat.
