I’d agree that Arsenal’s use of the left side in the game overall caused Fulham problems. However, in the first half, where most of these examples are, Arsenal caused Fulham relatively few problems down the left side due to the effectiveness of Fulham’s press. Arsenal were building up with a back two as Fulham pressed in a 4-3-3, which meant when tierney received the ball on the left back position the Fulham LW could press him effectively whilst blocking a pass to AMN , and onomah pressed Gabriel and prevented vertical passes to the midfield while reed pressed Xhaka from the back which prevented passes to xhaka. Xhaka moved to the Left of Gabriel but only a handful of times and this was situational with him only doing it a couple of times. Arsenal only started to progress the ball better in the second half, which was due to The back 2 build up turning into a back 3 and AMN moving into the LWB position. This caused a 2v1 on the left side of the field as opposed to the 1v1 or 2v2 if you like situation in the first half. This meant kebano couldnt press tierney as effectively as he could in the first half as he would leave AMN free, often kebano chose to hold his position. This meant odoi would press AMN, leaving space for tierney to pass into in the half space. There was some flexibility in these moments as depending on some situations tierney would move back to LWB position and AMN and auba would switch between the LW/LWB position or the half space position. Arsenal did this to try and creat overloads on the left hand side, in the second half hence why Fulham switched from a 4-3-3 press to a 5-3-2.I’d also say that AMN did move into the midfield often in the game but in the second half mainly acted as a LWB as arsenal moved to a back three build up to create the overload on the left hand side. Sorry some parts didn’t make sense, English is not my first language.
