BLOEMFONTEIN Celtic have pledged to complete a double over Polokwane City in their Absa Premiership clash at Kaizer Sebothelo Stadium in Botshabelo tonight.

But, Phunya Sele Sele striker Lerato Lamola said they need to be tighter at the back and ruthless upfront with City deep in the relegation mire.

The Free State outfit, who are doing well under Ernst Middendorp, pipped City 3-2 in the first round in Polokwane.

Celtic have lost once in their last six league matches - a 3-0 drubbing by Kaizer Chiefs, while 14th-placed City have been blowing hot and cold.

"We are delighted that we are in the top eight.

"We need to keep on doing well to continue moving up the ladder," said Lamola.

"City are fighting for survival, so we have to ensure we do not give them space to breathe.

"We have to shut the back door, but at the same time break their defence.

"We are going to push them deeper into relegation. I have been enjoying my first season in the PSL, scoring five goals to date."

The Limpopo-born Lamola - a graduate in criminal law - joined Celtic at the beginning of the season from National First Division side Roses United.

City coach Boebie Solomons is upbeat they will avenge the first defeat. "It is important that we remain as positive as ever, and we are going to Celtic to collect the three points."

City defenders Tlou Molekwane and Thapelo Tshilo will have to be at their best to stop Lamola and company.

When Celtic defeated City in the first round, Solomons was still employed by Celtic as a technical director, and it is yet to be seen how he will handle himself against his former employers.
