Short answer: No. Messi costs $5 and Ronaldo costs $5. Together they're $10 — leaving $0 for the other nine positions. Pick one.
Combined cost of Messi + Cristiano Ronaldo on TenDollarPick = $10 exactly. That uses your entire $10 budget on just two players, leaving zero for the other 9 squad slots (1 GK + 8 outfield). Since every player costs minimum $1, you'd need at least $9 more — impossible. The rule: you must choose. Messi vs Ronaldo comparison.
