And the 39-year-old believes that's why the Hammers boss was never destined to succeed at Newcastle.
"Sam Allardyce's style of play always seems to get people talking - something I know all about as it resulted in me leaving Newcastle United in 2007," Solano wrote in the Newcastle Evening Chronicle.
"As Newcastle fans will know, Big Sam was famed in his Bolton Wanderers days for playing a direct style of play that worked well to get them into the Premier League.
"You have to respect that. But I’m not sure it was ever going to work at St James’ Park. The style of play is basically the full-backs knocking the ball long up the pitch and often bypassing the midfield."
Solano, however, has acknowledged that Allardyce has adapted his style this season and seen great success with West Ham. It should be a fascinating encounter with his former club on Saturday.
