Martinez is about 124 mins per goal for all competitions.91 minutes per goal FFS...
we are looking for a unicorn if trying to replace Aguero.
we will just have to accept the improbable (a really good striker sub 100M) rather than chase the impossible
Though for just Serie A he is 176 mins per goal.
For 100m think I'd expect more.
Those stats suggest Mahrez level of goals.
