"Does changing the coach really make a struggling team shine again?" This question must have been on the minds of West Ham United fans countless times after hearing that Lopetegui was sacked and Potter took over. For a team hovering near the relegation zone, changing coaches is sometimes like betting, not knowing whether it's "winning big" or "losing all hope." And for Potter, this is more like a second venture full of unknowns. The news of Lopetegui's dismissal is not surprising. As the former head coach of West Ham United, his record during this season's coaching tenure is simply disappointing - the league ranking is close to the relegation zone, and the English League Cup was eliminated early. This team with huge investment not only failed to break through but fell into deeper trouble, making people wonder if this is still the historically renowned "Hammers"? Therefore, the decision-making level of the club chose to change coaches, which is not unexpected, but this decision seems to have come somewhat hastily and with a hint of helplessness. Speaking of Lopetegui, many fans would sigh, "This guy's luck is really too bad." He has coached many top teams - the Spanish national team, Real Madrid, Porto - but the results always fall short of success. He was sacked by the Spanish team shortly before the World Cup started because news of him coaching Real Madrid leaked in advance, directly ending his national team coaching career.

"Changing coaches is like changing knives," a phrase that sounds simple but doesn't always work on the football field. On January 8th, West Ham United, a Premier League club, officially announced the dismissal of their manager, Lopetegui, and quickly announced that former Chelsea manager Potter would take over the team. The question is: will this change in coaching really allow West Ham United to escape the mire of relegation, or will it just make them flounder even more in the mud? This is not an ordinary change of coach. This is a mid-table Premier League team's "life-or-death gamble" after continuous turmoil. For fans, Lopetegui's dismissal seemed to be foreseen: he led the team for half a season, only ranking 14th in the league, just 7 points above the relegation zone, and spent a whopping 144.4 million euros in the summer, which would be enough to make anyone's "teeth ache." Not to mention, they were eliminated early from the English League Cup, and West Ham United's performance on the field was completely disorganized. In theory, dismissing the coach is the beginning of "changing knives," but unfortunately, their newly selected knife—Potter—isn't exactly a reliable tool. Although he had the reputation of "father of the demon team" during his time at Brighton, his coaching experience at Chelsea was more akin to a disaster. The question is, can West Ham United still afford to take such a risk? Lopetegui is not a coach who has gained fame without substance. His resume looks even more impressive than many Premier League managers: he has coached Real…
