Hoeneß: We need to buy Jackson if he starts 40 games, which can't be achieved

This is another statement I don't understand, if Bayern Munich feel like making Jackson's deal permanent why not do so instead of coming up with this statement. Bayern Munich Chief Hoeneß knows it won't be possible for Jackson to start up to that number of games this season when they already have a balanced team and a better striker, so how can it be? Jackson can't even start up to 25 games this season even if he shows too much improvement than what we saw him display at Chelsea I still don't see Bayern Munich giving Jackson a chance.
