Amid a whirlwind of international football, the Nations League matches tonight bring both excitement and drama. New Portugal manager Jorge Jesus, 72, faces a significant challenge managing Cristiano Ronaldo, who at 41, struggles with form and expectations. After a win against Wales and a notable 2-1 victory over Norway, Ronaldo's absence in the latter sparked controversy, leading to his departure from the Portugal camp in frustration.

• Ronaldo's Form: Only one goal in eight matches since last November, along with a red card, raises questions about his role.
• Jesus’ Strategy: Starting Ronaldo against Wales but resting him against Norway has drawn mixed reactions, especially if Portugal falters against Denmark tonight.

In another key matchup, all eyes are on Erling Haaland as he represents a struggling Manchester City against Wales, who are desperate for a win after nearly a year without one.

Meanwhile, Germany under Jürgen Klopp seeks redemption after a shaky start, hoping to improve against Serbia following a draw and a loss to Greece. Off-pitch issues continue to overshadow their campaign as well.

The Republic of Ireland also faces challenges, with a fractured squad dynamic after their recent win over Israel. Goalkeeper Gavin Bazunu is back but will sit out the rematch with Israel, now moved to Serbia.

Tonight’s lineup includes:

• Wales v Norway
• Denmark v Portugal
• Germany v Serbia
• Republic of Ireland v Austria
• Greece v Netherlands
• Israel v Kosovo
• Malta v Gibraltar

Kick-offs set for 7:45 PM BST promise a night of thrilling football.
