If it wasn't clear before it is now, Arsenal mad a massive error in not signing Cesc Fabregas when it became apparent that he was heading towards the exit at Barcelona. Manchester United, too, should be kicking themselves about passing up the chance to sign him.
Instead of returning home to north London or to Old Trafford, the Spanish international pitched up at Chelsea and has been, well, amazing to put it simply. He's already got ten assists to his name and has helped the Blues to the top of the table where they look likely to stay until May.
Arsenal meanwhile...well, you don't need me to tell you about their form, do you...
It seems as though Fabregas enjoyed almost the perfect game in Chelsea's 2-0 win over West Brom on Saturday. The 27-year-old barely put a foot wrong as the Baggies were put to the sword at Stamford Bridge, and the game was effectively over when Eden Hazard scored Chelsea's second after 25 minutes.
"I don’t think I am exaggerating if I don’t remember playing and enjoying a football match as much as I did personally in the first half," Fabregas admitted afterwards. All things considered, it's going pretty well for him at Stamford Bridge then.
Indeed, there's plenty of evidence to back up not only Fabregas' statement, but also the claim that he is the best creative midfielder that the Premier League has ever seen. Firstly, no player in English football's top division history has provided 10 assists in as few as 12 games.
Next, Fabregas is right; he won't have played better in a half of football. Of course he got his assist for Hazard's goal, but the stats show more than that. He broke the record for the most successful passes in the final third in a Premier League game (since records began in 2006) with 64 - more than the 58 Paul Scholes achieved against QPR in 2012 - while he had the second most touches in a single Premier League game ever too, just one behind record holder Yaya Toure who managed 175 against Stoke in 2011.
The cherry on the cake? The Chelsea man not only made the most successful final-third passes he also attempted the most (72) in a single Premier League game. All together, it pretty much was the perfect game from the Spaniard.
And while Fabregas and Chelsea were stretching their lead at the top of the table, what were Arsenal doing? Losing to Manchester United of course to condemn to their worst start in 32 years.
Manchester United meanwhile are hardly faring much better even if they are fourth. The overall low quality of the league this season means they are just two points clear of Tottenham in 10th, and given how inconsistent they have been don't be surprised to see them tumble down the league.
Of course there is no guarantee that Fabregas could have changed either team's fortunes but there's no doubt he's in the form of his life and one of the best operators in the Premier League.
His next target? To climb up the all-time assist charts. As it stands he has 80 Premier League assists to his name, well behind current record holder Ryan Giggs, who managed 162 in his illustrious career. However Fabregas is averaging an assist every 2.5 games compared to Giggs who pulled one off every 3.9 games - so it might not be too long before he's officially the most creative player the league has ever seen.
