It is prudent for clubs not to travel too far for pre ssn. given they have players who just played almost 12 months non stop and secondly the dynamic covid situation.I think most of the clubs are returning to Pre ssn. on July 5th. excluding the players involved in Euro and Copa.Clubs like Chelsea,City,Man Utd who played an extra week of football owing to European competitions will probably return back sometime in 2nd week of July or early 3rd week.And if i am not wrong there is some summer competition in US where Italian and PL clubs are involved in US.
