Vale beat Fleetwood on the opening day of the League One season with Harrison coming off of the bench but was unable to affect the game. Harrison has adopted the ‘if you can’t beat them, join them’ approach, making the move just weeks after playing against Clarke.
Harrison had been linked with a return to Rovers back in January but joined Fleetwood, whilst the Gas spent money to prize away Ryan Loft from Scunthorpe United.
Taking credit for Harrison’s ascension in football, Clarke said to Vale’s official website:“I know a lot about Ellis because I made him, no disrespect to him, but Ellis would tell you that himself.
“He’s a physical presence, he can run, and he has a lot of excellent elements to his game, especially once we have the hunger back into his game and he’ll be a very good talent for us.
“When I had him at Bristol Rovers, we ended up selling him for a large fee to Ipswich, so I know very well about all his strengths, his character, how he is around the dressing room and that he is a winner.
“He also brings with him that pedigree at the League One level, and I know he is coming in hungry and ready to give his all. “I know he’ll liven up some of the group too with his bad banter as well!
“So, we’re really pleased to have been able to have gotten this bit of business done.”
Harrison came through the youth ranks at the Mem and ended up making over 205 appearances, scoring 52 goals for the club.
His best feat was scoring 12 goals in 44 appearances in 2018, achieving a 13th-placed finish which was one of their highest positions for a number of years.
Both Harrison and Clarke are due to make their returns to the Memorial Stadium on Saturday, December 22 before the return fixture at Vale Park on Saturday, April 22.
