Gorgie recruitment plans
Hearts boss Robbie Neilson is targeting signings as he strives to move the team closer to the Old Firm, while finishing in the top three in the Premiership once more. The Tynecastle Park club lost Saturday’s Scottish Cup final but will play at least eight European ties next season. Neilson said: “It’s important that we bring quality players in because I think the changes that Rangers could make [in the final] … we didn’t quite have that available. We need to try to get that. We need to try and get a real group of players here so that we come to Hampden and we can change things.” (Evening News)

When they don't give me the chance, I'm going to show everyone what I'm worth.

Forrest Hearts claim
Partick Thistle boss Ian McCall believes Hearts would be getting a winger better than James Forrest if they sign his brother Alan. The forward is out of contract at Livingston and is a key target for Robbie Neilson as he looks to strengthen his attacking options. McCall said: “The good news for Hearts fans is if they manage to pull off Shankland and Forrest then they'll improve in that area no end. So I do think they're light in the forward areas. I think now he's better than his brother." (BBC)
