Within the next two to three years, possibly sooner, Arsenal is going to have to find long term replacements for their two talismans, Pierre-Emerick Aubameyang and Alexandre Lacazette.
Neither has signed contract extensions and there remains a possibility that one or both will be sold next summer.
Even if they do sign extensions they are of an age that they are coming to the twilight of their careers, Aubameyang will be 31 next June and Lacazette will be 29 next May.
So, in the worst-case scenario replacements could be required within the next 12 months and best case, at least one replacement will probably be needed within the next three years.
There are three, maybe even more, players at Arsenal that should be ready to step into the shoes of either Aubameyang or Lacazette on a permanent basis in 12 months time, they are 19-year-old Reiss Nelson, 18-year-old Gabriel Martinelli and 20-year-old Eddie Nketiah.
Nelson and Martinelli are already in the first-team squad and Nketiah is scoring goals for fun on loan at Leeds United and even though Nelson is more a winger, so was Thierry Henry at one time.
All three will be gaining valuable experience this season, Nelson and Martinelli will no doubt be influenced by Auba and Laca and Nketiah is getting a proper education under Leeds manager Marcelo Bielsa.
Of course, Arsenal will be tempted to dip into the transfer market to sign an experienced proven striker if the need arises but it would be such a waste if none of the three youngsters I have named does not make the breakthrough.
Harry Kane, Marcus Rashford, Tammy Abraham and even Raheem Sterling when he was at Liverpool are classic examples of kids given the huge responsibility to lead the line at their respective clubs and you have to think that Nelson, Nketiah and Martinelli are as talented at their ages as what Kane, Rashford etc were at the same age.
