Alejandro Garnacho’s first outing for Aston Villa quickly became a talking point after the winger appeared to aim a subtle message at Chelsea on social media.

Garnacho featured in Aston Villa’s 3-1 win over the Indonesia All-Stars as Unai Emery’s side opened their preseason schedule. It was his debut for the club, and he used Instagram afterwards to reflect on the occasion with a line many interpreted as a pointed reference to his former team.

“First start in three months,” Garnacho wrote on Instagram. “Happy to be enjoying football again, 1% every day. Thanks Indonesia!”

The post followed a season in which he did not start any of Chelsea’s final five Premier League matches and scored only once in the league, making his departure unsurprising. But it also fit a pattern that has followed the winger through previous moves.

Garnacho had already left Manchester United after admitting he had started to do “some bad things” towards the end of his time at Old Trafford. He also drew attention in February when, ahead of Chelsea’s Carabao Cup semifinal against Arsenal, he said, “Everyone knows how hard it is to play there. If, for example, Manchester United can beat them there, we can do it perfectly.” Chelsea then lost 1-0, and Garnacho was mocked on social media by United supporters.

Later, after Chelsea lost 1-0 to Manchester United in the Premier League, Luke Shaw posted a picture of himself knocking Garnacho to the floor. Other United players commented beneath it, adding to the sense that relations had deteriorated.

Garnacho has often generated headlines when leaving clubs, and this latest message after his Aston Villa debut will only add to that reputation. Yet the bigger issue now is his output on the pitch. United once viewed him as a major talent after his breakthrough in the 2022-23 season, but this stage of his career may depend on whether he can make the right kind of impact in 2026/27.

With less than a month left in the transfer window, Premier League clubs are still expected to be busy. Incomings and outgoings remain likely across the division, and every side still appears to have at least one clear gap to fill before the deadline.

Arsenal may be attracting attention with their pursuit of Vinícius Júnior, but their bigger need is in central midfield. Declan Rice carried too much of the load last season, while Martín Zubimendi faded after the break and Myles Lewis-Skelly is not yet fully trusted there. Another box-to-box midfielder would help enormously.

Aston Villa could soon be short at left back if Lucas Digne leaves, which would leave Ian Maatsen as the only senior option. Bournemouth need more depth in wide areas, Brentford still require a more natural left back, and Brighton & Hove Albion must replace the goals lost with Danny Welbeck’s move to Chelsea.

Chelsea, meanwhile, have done plenty of work already but still have not addressed the goalkeeper position. Robert Sánchez improved in 2025-26, yet the club still look in need of a top-class solution.

Elsewhere, Coventry City are close to signing Carl Rushworth permanently and would then turn to left back. Crystal Palace need centre-back reinforcements after losing Marc Guéhi and Maxence Lacroix, while Everton must add a defensive midfielder after Idrissa Gana Gueye’s departure.

Fulham will look for winger depth after strengthening up front, Hull City want more options in attack, and Ipswich Town are still waiting for a central midfielder. Leeds United may also need another striker to cover for Dominic Calvert-Lewin’s injury record.

Liverpool’s most pressing issue is out wide, Manchester City need a right back, Manchester United still want a more destructive midfielder, and Newcastle are alarmingly short at left back. Nottingham Forest must replace Elliot Anderson in midfield, Sunderland need more balance on the left side, and Tottenham Hotspur have already moved aggressively to rebuild after last season’s collapse.

The Premier League remains a ruthless place for managers, and the 2026/27 season begins with that reality clearer than ever. A summer of upheaval has left dugouts across the division occupied by a fresh wave of appointments, while one club is still waiting to name a new head coach.

At the top of the list, Mikel Arteta stands alone as the league’s longest-serving manager. Appointed by Arsenal on Dec. 22, 2019, he has outlasted every other current rival and remains comfortably ahead of the pack. Behind him comes Unai Emery, who has been in charge of Aston Villa since Nov. 1, 2022, followed by Daniel Farke, who took over Leeds United on July 4, 2023.

Further down the rankings, the turnover becomes even more obvious. Régis Le Bris and Fabian Hürzeler both arrived in July 2024, while Frank Lampard, David Moyes, Sergej Jakirović, Keith Andrews and Michael Carrick all joined their clubs during 2024 and 2025. The list then tightens further still, with a cluster of appointments made only months before the new campaign.

There are notable cases throughout. Roberto De Zerbi, hired by Tottenham Hotspur on March 31, 2026, sits just outside the top 10. Michael Carrick is inside it after first being named interim Manchester United boss in January and then permanently hired in May. At the other extreme, Álvaro Arbeloa is the latest arrival, taking charge of Fulham on July 7 after an unsuccessful spell as Real Madrid boss.

A number of other clubs have also changed course recently, including Chelsea, Liverpool, Manchester City, Nottingham Forest, Ipswich Town, Crystal Palace and Bournemouth. Over half the division has turned to new managers in 2026 if Newcastle United are included, with the club still yet to appoint Eddie Howe’s successor.

For now, Arteta remains the benchmark for staying power in a league that rarely gives managers much time.
