Rogers and Chelsea's blueprint

[Getty Images] It took Morgan Rogers only seven minutes to score his first goal in a Chelsea shirt in Saturday's 3-1 friendly win over Real Sociedad as he reacted quickest after Alex Remiro saved Joao Pedro's initial header. The £117m club record signing from Aston Villa initially looked sharp and linked well with Cole Palmer and Pedro in Chelsea's front three. Within 10 minutes of his debut, supporters were already chanting his name. However, it was understandable that Rogers faded as the match wore on, given he had trained for less than a week since returning from holiday before his 62-minute outing. Beyond Rogers, Joao Pedro has been the star of Chelsea's pre-season. In this outing he headed Chelsea back in front in the 47th minute before adding a side-footed finish 30 minutes later to seal victory after Sociedad had equalised just before half-time through Jon Mikel Aramburu's volley. Chelsea lost control towards the end of the first half and looked vulnerable, but they were much improved after the break. Joao Pedro has scored eight goals in seven pre-season matches and led the line with Rogers and Palmer operating behind him. Alonso offered a glimpse of the 3-4-2-1 formation he could use at Fulham in Chelsea's Premier League opener as he took charge of a match at Stamford Bridge for the first time. It featured Robert Sanchez as the first-choice goalkeeper, with Wesley Fofana, new signing Maxence Lacroix and Levi Colwill forming a back three - from right to left. Pedro Neto operated at right wing-back and Marco Palestra on the left, while captain Reece James and Moises Caicedo lined up in midfield behind the front three. There was also a debut from substitute wing-back Pep Chavarria, although a number of notable players were absent. Of course, Alonso insists he won't be wedded to either a back three or four but it was this system used as Chelsea beat AC Milan 3-0 a week ago.
