#1 The rise of "fringe" players
A team cannot win a league which is as demanding as the Premier League with just 11 good players, and recently Chelsea have shown that they have a squad of hugely talented players.
Victor Moses had rarely been missed, as Davide Zappacosta slotted in beautifully and put in amazing performances in the last few weeks. His speed down the right flank and whipped crosses have been a nightmare for defenders, as Swansea's Alfie Mawson will agree.
Then Victor Moses returned to the starting line up against Newcastle and was one of the most important players on the pitch with 2 assists.
Willian has also come to the fore in recent weeks after being temporarily sidelined. His brilliant brace against Qarabag followed by the equalizer against Liverpool (of course he meant it!) was backed up by another good display against Swansea. He has proved that it is not yet time to write him off the Chelsea roster.
Danny Drinkwater has almost come back to full fitness as was evident in the marauding runs forward in the match against Liverpool. He kept Coutinho within reach at all times in the first half and played the full 90 minutes against Newcastle.
With the current bench that boasts of Willy Caballero, Antonio Rudiger, David Luiz, Danny Drinkwater, Tiemoue Bakayoko and Michy Bathsuayi, Chelsea will surely be able to mount a challenge for the title, and threaten to knock Manchester City off of their high perch.
