Released Manchester United striker Radamel Falcao is full of praise for Colombia teammate Jackson Martinez.

The Porto centre-forward is a top summer target for Arsenal.

AS Monaco striker Falcao, who is in talks with Chelsea, will play with Martinez at the Copa America this summer.

"He's had a fabulous season, he was a protagonist for his club.

"What he's achieved is a great source of pride for all of Colombia," said the former Porto star.
