Aston Villa boss Paul Lambert is delighted with the current form of Carlos Sanchez.
Lambert said Sanchez is now finding his feet after being thrown into the side at the last minute against Arsenal in September.
"It was unfair throwing him into the Arsenal game for his debut after Ashley Westwood pulled out.
"We threw him in and it was a hard call that. I knew what kind of player we were getting. He could fit anywhere, but it still takes time
"He's got 50-odd caps for Colombia and they are no mugs. He could prove to be the bargain of the season at £4m."
