Currently there are many names that England is considering to bring a new name to its training bench and the closest is Potter and he is also of British nationality but considering that he is not a suitable name, in my personal opinion England has the opportunity to bring Guardiola to manage the England national team because he is has proven that he can handle teams with big names and I think Guardiola is the most suitable to fill the England coaching bench.
Now there are several coaches being rumored and Guardiola is even the main target to be able to handle the English team, but I think it will be difficult because so far Pep Guardiola has never been a national team coach.
However, with the squad that England currently has, especially the many potential young players they have, I am optimistic enough about the attractiveness of becoming a top coach to want to accept this job.
If the benchmark is a trophy obviously Southgate was failed because although he can bringing England to advances to the final matches of Euro Cup two times in a row but in fact until now England still no trophies under him but if we see from the statistics obviously England under Southgate is very impressive because when train this team Southgate can bringing England to gets runner up of Euro Cup 2 times and semifinal of world cup and England too can gets 3rd place of Nation League on 2019
I have discuss about this before because seems Guardiola is the strongest candidate to be the manager of England even England has willing to wait until Guardiola contract expired with Manchester City but besides Guardiola i found at least 4 candidates such as Eddie Howe, Maurico Pochettino, Graham Potter and the latest is Thomas Tuchel
