Man Utd defender Ferdinand backing Spurs skipper King for World Cup
For the win over Mexico, Ferdinand was certain King had done enough to convince Fabio Capello his body can stand up to the rigours of a four-week tournament.
Ferdinand said: "Ledley's a good player and good players play well alongside other good players.
"I enjoyed it. We both enjoyed it. He got a goal as well, which was great.
"From set-pieces everyone knows we are fairly decent and in the tournament hopefully that bodes well for us.
"Ledley had a great chance to show the manager what he can do and I thought he did a great job.
"Mexico qualified for the World Cup and they are a good team. We knew we were in for a tough game but by the end of it we were the team that controlled it."
