"Expect A Battle": Alphonso Davies Warns Lionel Messi's Argentina Ahead Of Copa America Semi-Final

The Copa America is down to the final four with a pair of fascinating semi-finals and favourites Argentina hoping they can win their third straight major title. The Argentines, world champions and defending Copa title holders, open the semi-final action when they face surprise package Canada on Tuesday in New Jersey. Then on Wednesday in Charlotte, Uruguay -- who knocked out Brazil after a shoot-out on Saturday -- will play a Colombia team which, unbeaten in 27 games, beat Panama 5-0 in their quarter-final.

Argentina and Uruguay, currently tied on 15 Copa America titles, are both hoping they can break that deadlock to become the most successful nation in the tournament's history.

Colombia have a solitary title from 2001 while Canada are playing in the tournament for the first time.

Argentina needed penalty shoot-out heroics from their goalkeeper Emiliano Martinez to get past Ecuador in the last eight and while Lionel Scaloni's team have yet to really hit top gear they start as clear favourites against Canada.

American coach Jesse Marsch has made an instant impact with Canada, taking over in mid-May and quickly implementing his high-energy, pressing style to great effect.

Marsch, who was reported to be close to taking over as USA coach before the decision last year to re-hire Gregg Berhalter, has had the last laugh as his team have produced a memorable run to the last four while the Americans failed to get out of their group.

Canada got past a Venezuela team that had won all three of their group stage games, winning on penalties at the end of a pulsating encounter on Friday.

However, they know that Lionel Messi and Argentina represent a very different proposition.

The teams met in the opening group game of the tournament
