Morgan Rogers scored on his debut and Enzo Fernandez received a mixed reception from the Chelsea support as Xabi Alonso won his first match at Stamford Bridge, a 3-1 victory against Real Sociedad.Rogers, signed for £117million ($158m) from Aston Villa this summer, opened the scoring from close range in Chelsea’s final pre-season friendly and Joao Pedro scored twice in the second half, while Jon Aramburu was on the scoresheet for the visitors.On Wednesday, Chelsea had imposed a deadline for Manchester City — or any club — to lodge a £120million offer for Fernandez before 5pm on Friday, but they received no bids.The Argentina international was booed by some Chelsea fans when his name was read out and when he was brought on in the second half, but there were more supporters chanting his name.Simon Johnson analyses the key talking points from Stamford Bridge…How did £117m Rogers do on his Chelsea debut?When you cost a club and British transfer record, you want to get off to a good start. Even in a pre-season friendly.That is exactly what happened for Morgan Rogers for Chelsea this afternoon, getting his first goal at Stamford Bridge in his first appearance.Sure, it was just a tap-in after Alex Remiro had got a hand to Joao Pedro’s fine header. But right place, right time and all that.Rogers tucks the ball home from within the six-yard box (Ryan Pierse/Getty Images)For the first half of the first half, he showed why Chelsea have spent £117million on him. Rogers outshone fellow No 10 Cole Palmer, causing Real Sociedad a few problems from the left pocket.As the half wore on, some rust and lack of sharpness crept in. It is understandable. Rogers only began training with his new team for the first time on Tuesday, having been given an extended holiday post World Cup.Despite this, Rogers came out for the second half too and within minutes sent in a delightful cross, this time from the right, which no team-mate was ready for at the back post.The England international came off just after the hour mark, a very useful run-out to get some much-needed minutes into his legs. There is a lot more to come from Rogers, but this was a good way to begin winning over the crowd.
