Blackpool manager is hoping that he can add four more to his squad before the end of the transfer window on Monday.
Riga has until the end of Monday to make the additions that he requires to his squad.
All hasn’t gone to plan so far for Riga as he has tried to rebuild the squad from its barebones that he took over from.
Riga told the Blakpool gazette
“I think we need a midfielder, a centre back, a winger and another striker,” he said.
“We maybe need a striker who is a bit different and maybe has more pace, and a powerful type of midfielder.
“So four very good players will make me very happy and we need it.”
After Monday evening the only transfers that will be allowed is emergency loans until January, when the window re-opens for the month.
