Alan Smith has credited Arsenal`s Per Mertesacker for speaking candidly about the mental and physical burden professional football can bring.
The 33-year-old defender, who is set to become Arsenal`s new academy manager for the 2018/19 season, spoke of the intense pressure involved and admitted he would .
Mertesacker said: Some days you realise that everything is a burden, both physically and mentally... but you have to deliver without a doubt, even if you are injured.
Former striker Smith, who made 264 appearances for Arsenal, says players facing similar problems as Mertesacker in their careers is not uncommon.

It`s a side of professional football that the public don`t see. It`s constant, it`s always on you.
