Omar Daley says international team-mates Ricardo Fuller and Theodore Whitmore persuaded him that a move to Motherwell would be a good career move.
The 30-year-old Jamaica winger signed a two-year contract this week after being released by Bradford City.
Stoke striker Fuller had a spell at Hearts and Whitmore was at Livingston.
"I spoke with Ricardo, my mate who played in Scotland, and the head coach of the national team, Theodore Whitmore, was also here," said Daley.
"Obviously speaking with Stuart McCall and having worked with him at Bradford was enough ammunition to get myself up here."
Daley first came to British football in loan spells with Reading and Preston North End from Portmore United in his homeland.
After 10 months in the United States with Charleston Battery, he won a move to Bradford in 2007 and, during his four years there, played under Motherwell manager McCall.
"He's been nothing but good to me and his management skill is very good - and he is an honest man," said Daley.
The winger ended last season on loan to League Two rivals Rotherham United before his summer release.
However, he had retained match fitness while playing for his country in the CONCACAF Gold Cup and won his 65th cap for the Reggae Boys this month against Columbia.
Now, after a successful trial with Motherwell, Daley is looking forward to battling with fellow speed merchant Chris Humphrey for a starting place on the right wing.
However, McCall pointed out that he also used Daley on the left and through the middle at Valley Parade.
"I needed to look at him again because, when I had him at Bradford, he was flying and could have gone on and played in the Championship the way he was playing," said the manager.
"Unfortunately, he got a knee injury and he was out for eight or nine months I think and it culminated in us falling away, because we were looking as though we were going to get promoted, and we missing just missed the play-offs.
"I needed to have a look at him to see if he had overcome that - and he has and he is as quick as ever.
"He's exciting, he's entertaining, he's a threat, there's no doubt about it.
"He can be inconsistent, as you get with wingers, but he's matured since I knew him and, if we can get the best out of him, I am sure he will do well."
