Transfer trades of the week: Maxence Lacroix to Chelsea, Christos Tzolis to Arsenal & all the biggest done deals of the summer window

Aston Villa continue to be busy during the summer window as they added Alejandro Garnacho to their ranks, the Argentina international arriving on a season-long loan deal from Chelsea. Garnacho struggled for much of his debut season at Stamford Bridge, and scored just one Premier League goal following his switch from Manchester United. Villa boss Unai Emery, then, will be tasked with revitalising the 22-year-old over the next 12 months.

Daizen Maeda confirmed his status as a modern Celtic legend after his goals fired the Bhoys to a domestic double towards the end of last season, but he has now left Parkhead behind after completing a move to the Premier League with Ipswich Town. Japan international Maeda departs Celtic having scored 79 goals in 212 appearances for the club, and will now be tasked with ensuring Ipswich do not suffer relegation back to the Championship at the first time of asking yet again.

Celtic did, however, move quickly to reinforce their attack by acquiring striker Kasper Hogh. The Denmark international was one of the revelations of last season's Champions League as his goals helped Bodo/Glimt secure victories over Manchester City, Atletico Madrid and Inter on their way to reaching the last 16. Now, Hogh is bringing his talents to Glasgow and the Scottish champions.

Karim Adeyemi never quite lived up to the hype at Borussia Dortmund following his breakout at Red Bull Salzburg, but that has not put Barcelona off bringing in the Germany international. Lightning fast and with decent finishing ability, Adeyemi promises to add an extra dimension to Hansi Flick's forward line as he reunites his former national team coach in Catalunya.

Monaco have shown an eye for attacking talent in recent years having tasted success with the signings of Folarin Balogun and Mika Biereth, and they will hope to have struck gold again with Matthis Abline. The 23-year-old arrives from Nantes having scored 24 goals across all competitions during the past three seasons, though his efforts weren't enough to keep his now-former club from suffering relegation to Ligue 2 in 2025-26.

Roma secured their first signing of the summer as they prepare to return to the Champions League by acquiring Argentine striker Santiago Castro from Bologna. The 21-year-old arrives in the Italian capital having produced 33 combined goals and assists in his two-and-a-half seasons in Serie A, and will wear the No.9 shirt for the Giallorossi after Artem Dovbyk moved in the opposite direction.

Despite their Premier League title success, Arsenal are not looking to rest on their laurels, and made their first big-money signing of the summer with a move for Club Brugge forward Christos Tzolis. The Greece international arrives in north London following a red-hot final campaign in Belgium that saw him score 22 goals and provide 29 assists, and Tzolis will now be entrusted with filling the gap left in the Gunners' squad by Leandro Trossard's departure for Besiktas.

Atletico Madrid bid farewell to club legend Antoine Griezmann at the end of last season, and the Rojiblancos have now gone some way to replacing the attacking midfielder by bringing in Kang-in Lee from Paris Saint-Germain. The South Korean spent three seasons at Parc des Princes where he collected plenty of medals but was mostly restricted to cameos off the bench. Atleti clearly believe in his talent, however, and have brought Lee back to La Liga, where he previously caught the eye for both Valencia and Mallorca.

Not the most headline-grabbing of Chelsea's summer transfers, but Maxence Lacroix could prove to be one of the most important. The Blues have struggled to nail down a regular partnership at the heart of their defence, but brining in France international Lacroix, who is proven in the Premier League following a successful two seasons at Crystal Palace, should bring some consistency to Xabi Alonso's backline in west London.

Saudi Pro League clubs still have plenty of money to spend, and Al-Hilal have dipped into their cash reserves to secure the signature of Crysencio Summerville from under Roma's noses. Summerville was one of West Ham's standout performers last season despite their relegation from the Premier League and impressed for the Netherlands at the World Cup. The 24-year-old winger should, then, thrive in the Middle East.
