Josh Acheampong spent a long time waiting for an opportunity in his early Chelsea career. Now, the twenty-year-old is making it nearly impossible for Xabi Alonso to leave him out of the starting lineup.

His impressive displays this term have won over skeptics, making him arguably the biggest beneficiary of Alonso taking charge at Stamford Bridge. However, Sunday's match against Manchester United will present his toughest test yet.

Acheampong has featured in the starting XI for six of Chelsea's previous seven fixtures, securing a regular spot in a squad where competition is intense and reputations carry little weight under Alonso. With Maxence Lacroix sidelined by injury, the England youth international could shoulder even greater responsibilities against a visiting United side eager to prove themselves.

Among Chelsea defenders, only Lacroix and Levi Colwill have logged more minutes this season. This represents a massive shift for a player who previously struggled for regular action. Acheampong has looked equally comfortable as the right-sided center-back in a back three and as a traditional right-back within Alonso's 4-4-2 formation.

His partnership with Pedro Neto down the right flank has blossomed into one of the brightest aspects of Chelsea's campaign, with the two developing a nearly telepathic connection. Meanwhile, Malo Gusto and Palestra have found minutes hard to come by, and club captain Reece James is increasingly deployed in midfield when fit.

James' physical restrictions following years of injury struggles play a part in this, but it also highlights the confidence Alonso places in Acheampong. Observers at Cobham note this progress is no accident, as the academy product has long been viewed as a standout prospect. Former captain John Terry previously called him a special talent and part of the future of Chelsea Football Club.

Patience and discipline have always separated Acheampong from others. While peers like Alfie Gilchrist and Tyrique George sought first-team minutes elsewhere, Acheampong chose to stay and wait. Mauricio Pochettino handed him a senior debut against Tottenham in May 2024, though that brief outing gave little hint of what was to come.

Following Pochettino's departure, Enzo Maresca handled his development carefully while contract and future questions swirled. Maresca noted at the time that the player could potentially become very important for Chelsea. Yet, with managers changing frequently at the club, Acheampong also worked under Liam Rosenior before Alonso arrived to provide a clean slate.

During a preseason tour of Australia and Asia, Alonso informed the defender that playing time would depend strictly on performances. Since then, Acheampong has elevated his game, displaying the maturity and confidence that makes him one of the first names written down for the defense.

A major decision regarding his future also approaches. Acheampong is contracted until the summer of 2029, having previously drawn strong interest from Bournemouth and Crystal Palace. He prefers earning improved terms through his play rather than letting contract talks become a distraction. Chelsea may face a pivotal choice next summer when both Acheampong and Wesley Fofana reach the final two years of their agreements.

For now, attention centers entirely on Manchester United. Lacroix's absence forces Alonso into a tactical choice, questioning whether to keep Acheampong at right-back alongside Neto or move him central to partner Colwill. Either choice demonstrates how vital the youngster has become to the team.
