Atletico Madrid chiefs are drawing up plans to bring in a new striker over the summer.

Whether Sergio Aguero sticks or twists won't matter to Atletico directors, who have Porto striker Lisandro Lopez and Lazio's Mauro Zarate both on their radar.

Both Argentines are rated at around £16 million by their clubs, with Zarate on-loan at Lazio from Qatar's Al Sadd.
