Danny Murphy believes Arsenal would "struggle to replace" captain Martin Odegaard if he suffered an injury during the run-in.
The Gunners are seven points clear of Manchester City at the top of the Premier League table and on course to win their first title in 19 years. There's still a long way to go, though, as they have to play Pep Guardiola's champions twice and fulfil 20 other fixtures.
Odegaard, 24, has played a key role in Arsenal's title charge, scoring seven goals and providing five assists in 15 Premier League outings. He was at his brilliant best during the 4-2 win against Brighton on New Year's Eve, as he picked up a goal and an assist.
