Southampton will hope to keep former talisman Dexter Blackstock off the scoresheet when they travel to QPR on Sunday.
Blackstock, who left Saints two years ago, has made a fine start to the new
season with three goals from five appearances.
But Jan Poortvliet is hopeful his side will keep the 22-year-old striker quiet in a bid to kick-start their own campaign and begin a move up the Coca-Cola Championship table.
QPR are in good shape having collected seven points from four matches in the Championship and the Saints, after three defeats from four, are wary of the Londoners' threat.
Poortvliet told the club's official website the Saints need to be wary of QPR's strikers, who have found the net five times so far this season.
He said: "Dexter Blackstock is dangerous and he's always in dangerous positions, so we have to look out for that. Some of our players know him, but on a good day we don't have to fear anyone."
Blackstock, 22, will be one of three former Saints in the Rangers set-up hoping
to get the better of their old club at Loftus Road, along with manager Iain
Dowie and his assistant Tim Flowers.
Former England goalkeeper Flowers, who spent seven years at The Dell, has also been impressed with Blackstock's performances this term, especially since he has been deployed as a lone striker.
Flowers added: "It was born out of necessity, having to switch. After
the Sheffield United game [a 3-0 defeat] we came to the conclusion we were not built for 4-4-2, it was kamikaze stuff.
"It meant Dexter was up on his own but he has worked tremendously hard. You
have to put a shift in on your own.
"He is a handful and has got his goals, which he has deserved."
Blackstock scored four goals in his 28 games at Southampton, including a Carling Cup hat-trick against Colchester United.
