Sound-out:
格 (gé) → 'Gre-,'
丽 (lì) → '-li-,'
尔 (ěr) → '-l-' (the English liquid 'l/r'),
思 (sī) → '-sh' (an approximation, since Mandarin lacks a true final 'sh'). Together they walk through 'Grea-li-l-(i)sh' → Grealish, the name of English footballer Jack Grealish (Manchester City, England national team).
