Greenslade initially joined Bristol Rovers at the under-7s level. During the 2021–22 season, he was loaned out to Southern Football League Division One South club Cinderford Town and Premier Division club Tiverton Town, interspersed with a successful stint at Hellenic League Premier Division club Tuffley Rovers.

In May 2022, Greenslade secured his first professional contract with Bristol Rovers after being invited to train with the first team during the latter part of the previous season. He made his senior debut on 30 August 2022, coming off the bench in a 1–1 EFL Trophy draw against Plymouth Argyle, though he missed a penalty in the subsequent shootout loss.

On 6 September 2022, Greenslade joined National League South side Chippenham Town on loan until January 2023. In February 2023, he was loaned to Truro City for one month, with the loan later extended until the end of the season. His spell at Truro ended with promotion. Although he was an unused substitute in the play-off final, he had previously scored a penalty in the semi-final shootout victory. At the end of the 2022–23 season, he was offered and signed a new one-year contract on 6 June.

On 12 August 2023, Greenslade returned to Truro City, now in the National League South, on a one-month loan, scoring on his second debut in a 3–2 defeat to Braintree Town. His loan was extended by a further month on 8 September.

On 3 February 2024, Greenslade joined National League side Oxford City on loan until the end of the season. It was announced on 1 May 2024 that he would leave Bristol Rovers at the end of his contract in June.

On 29 May 2024, Yeovil Town announced the signing of Greenslade following the expiry of his contract with Bristol Rovers.
