A team that has recently been relegated to J2, can’t necessarily get promoted back to J1 the next year so easily. There’s a lot of competition.
ご質問ありがとうございます。
まず、「J2降格チームが翌年昇格できるとは限らない。」は英語で「A team that has recently been relegated to J2, can’t necessarily get promoted back to J1 the next year so easily. 」と言います。
また、「戦力は拮抗」は英語にすると「There’s a lot of competition. 」になります。
最終的に「A team that has recently been relegated to J2, can’t necessarily get promoted back to J1 the next year so easily. There’s a lot of competition. 」になります。
ご参考になれば幸いです。
