Tim Sherwood is set to axe several Aston Villa players after their FA Cup dreams were crushed by Arsenal at Wembley.
Monaco striker Radamel Falcao is speaking to Chelsea about a possible transfer, Sky sources understand.
Pochettino has yet to make a new signing since he moved to Spurs from Southampton in May, but the arrivals of goalkeeper Michel Vorm and defender Ben Davies from Swansea City appear to be imminent.
Spurs are also favourites to land Morgan Schneiderlin from Southampton ahead of north London rivals Arsenal, but it is unlikely to be a summer of activity to match 2013, when seven players were recruited for near to £100m around the sale of Gareth Bale to Real Madrid.
The Argentine coach is hopeful about making more signings, but is broadly satisfied with the squad he inherited.
"We are very pleased with our squad," Pochettino declared.
"The club made a big investment last season and we have an unbelievable squad.
"We always need to improve and it is possible we will add some players, but there will not be many changes."
