Real Salt Lake coach Jason Kreis has heaped praise on former teammate Jeff Cunningham, who is on the verge of becoming MLS' all-time leading scorer.

The pair played together at Salt Lake in 2006/07 and Kreis said the 34-year old FC Dallas striker's consistency was quite remarkable.

"I would say nothing short of incredible," said Kreis. "If you average his goals over the number of seasons he's played, you get an impressive number.

"It's one thing for forwards to have a good year here, and a good year there but him doing it on a consistent basis and to average it up and it turns into the number he has - it's just impressive, very, very impressive."

Cunningham gets the chance to go past the record he shares with DC United's Jaime Moreno of 132 MLS goals when Dallas take on DC this weekend.
