Like all managers who have made the step up to managing a big club, yes, Graham Potter does need time to implement his system. But he also needs the right players to implement his style of play out on the pitch.
At both Ostersunds and Brighton, he had an environment where he was trusted and given time by both clubs, and that enabled him to build somewhat successful teams. Joining Ostersunds in 2010, Potter took the Swedish outfit from the fourth tier all the way to the top flight over the next few years, while also winning the 2017 Swedish Cup. That cup win got them entry into the qualifying rounds for Europe, and the club would go on to make it to the knockout stages of the Europa League, being eliminated in the round of 32 by Arsenal.
At Brighton, Potter took a team who were usually reliant on defending deep and scoring on the counter-attack, to a side that were comfortable in possession and able to go toe-to-toe with some of the division's best sides. Whereas the Seagulls were previously reliant on moments of brilliance from their top players like Pascal Groß or Glenn Murray to gain points.
The South Coast club's excellent recruitment got Potter the players he wanted, and Brighton would no longer have to rely on one or two star players - they were now a team with some top-quality talent. Alexis Mac Allister, Marc Cucurella, Leandro Trossard and Tariq Lamptey are arguably the best examples of the smart business that Brighton conducted.
Lamptey and Cucurella were excellent wing-backs, both offering serious attacking threat going forward. Crucially, they were also adequate when it came to defensive duties. Brighton's goals conceded have gone down every year since the 2018/19 season, and the duo played a part in achieving that alongside regular centre-back Lewis Dunk - the duo were also key in creating chances for Brighton's attackers from the flanks.
Mac Allister brought dynamism and creativity in midfield, while Trossard is a goalscoring threat from both the left- wing and whenever he has played centrally. Potter went on to guide the club to 15th, 16th as well as a ninth-place finish in his three full seasons in charge. While on paper those first two finishes are not outstanding, Potter's football was widely regarded as one of the best in the league to watch, and he did a fantastic job with such limited resources. At a much better-resourced Chelsea, Potter could arguably produce much better results - and in doing so, he could perhaps add some silverware to his limited medal haul.
