Alonso's 2026/27 season, read from the numbers

In 2026/27, Marcos Alonso was used in rotation for Celta Vigo in the La Liga: 5 appearances and 411 minutes, averaging 82 minutes per outing. His standout number is match rating — 82nd of 905 defenders and inside the top 9%.

Per 90 minutes that is 1.8 tackles per 90, 2.2 interceptions per 90 and 56% of his duels won — the rate profile behind Alonso's totals. The profile is lopsided rather than complete: measured against defenders, Alonso sits in the top 20% for chance creation but only the top 59% for shot conversion.

Set against Alonso's own record, 2026/27 reads differently: he is playing far less than he once did — 501 minutes against 2860 at his peak; his average match rating has slipped from 7.06 to 6.01 since 2025/26. Discipline is part of the picture for Alonso: 2 bookings in 5 appearances, one every 2.5 games and 1 red card.

Our records cover 12 seasons of Alonso's career, 2015/16 to 2026/27, across 4 clubs — Fiorentina, Chelsea, Barcelona, Celta Vigo. In that time he has played 398 matches across 11 competitions, 30,413 minutes in all. His best season on our records was 2021/22, when he averaged 7.15 across 46 appearances.

Alonso has 55 appearances in UEFA Europa League and UEFA Champions League on our records, and the gap is real: he is roughly 1.6 times more productive domestically, 0.13 per 90 domestically against 0.08 in Europe. Away from his club, Alonso has 6 appearances for Spain on our records — across UEFA Nations League.

On our positional score Alonso rates 39 out of 100, 101st of 304 qualified players — inside the top 34%. Relative to what each component is worth, his strongest is interceptions.

How these scores are built, and the minutes and rating floors a player must clear to appear on our boards, are set out in our methodology.
