Leeds United have warned suitors off teenage starlet Jack Clarke.

Southampton boss Ralph Hasenhuttl has joined Manchester City rival Pep Guardiola in showing interest in the 18-year-old Clarke because of his storming debut campaign for Leeds.

But Leeds are adamant academy-product Clarke is not for sale and want the winger to grow with them, hopefully next season in the Premier League, reports the Mirror.

Leeds have shown their faith in Clarke by handing him the biggest contact for an Under-18 player in their history and his deal has three years left to run.
