The suspension of Thomas Partey for the first leg of the UEFA Champions League semifinals against Paris Saint-Germain forces Arsenal to rearrange their midfield. The 2-2 draw against Crystal Palace offered several clues about the new setup planned by Mikel Arteta.

Mikel Merino Set to Drop Deeper

The first adjustment involves Mikel Merino moving back into midfield. The Spanish midfielder, who had been filling in as a forward due to injuries to Kai Havertz and Gabriel Jesus, will return to his natural position alongside Martin Ødegaard and Declan Rice. This trio was already tested during the 4-0 win over Ipswich Town.

Merino's tactical awareness and technical quality could be key for controlling the tempo at the Emirates Stadium. Moreover, when Arsenal goes on the attack, the former Real Sociedad player is expected to act as an additional offensive weapon.

Trossard Likely to Lead the Attack

With Mikel Merino dropping back, Leandro Trossard will likely spearhead Arsenal's frontline. The Belgian striker, who came off the bench against Real Madrid, is enjoying a strong run in the Premier League, scoring in each of his last four starts.

Trossard's constant movement between the lines could trouble PSG's central defenders, although his lack of physicality might give an advantage to players like Pacho and Marquinhos. Had Merino stayed in the false nine role, Arsenal could have exerted greater physical pressure on the French side’s defense and created more space for wingers like Bukayo Saka and Gabriel Martinelli.

Lewis-Kelly, the Young Talent to Watch

The absence of Thomas Partey will also impact the physical balance in midfield. Declan Rice will sit deeper in the trio, limiting his forward runs. In possession, Myles Lewis-Kelly will step into central areas to support ball progression.

The 18-year-old Englishman impressed against Real Madrid with his ability to break lines. Facing a technically gifted midfield like PSG's, his positioning could be crucial in determining the outcome of the semifinal clash.
