As we reach Christmas and approach the midway point in the Premier League season, the time has come to reflect on the first half of a campaign that has delivered drama and unexpected twists in abundance. It's also the opportune moment to assess those players who completed a transfer to, or within, the English top-flight back in the summer, with a decent sample size of games now under their belts.
This time last year, the narrative around Chelsea's meeting with Arsenal at Stamford Bridge focused on whether Cole Palmer had reached Bukayo Saka-levels of stardom. He had taken west London by storm during his first year with the Blues and was spearheading an unlikely title charge through the autumn. Now, though, the debate between the two rivals has shifted to midfielders Moises Caicedo and Declan Rice.
