Watford manager Malky Mackay praised Heidar Helguson's maturity after the striker celebrated his second `debut' for the club with two goals that almost completed a memorable turnaround against Leicester.

The 32-year-old rejoined the Hornets on Tuesday on loan from QPR after four years away, having scored 64 goals during his initial five-and-a-half years with the club.

The Iceland international was introduced at the start of the second half with his side trailing 2-0.

After almost scoring with his first touch, Helguson played a part in Watford's first goal before scoring twice himself to put them 3-2 up. But the home side's hopes of a third straight win were dashed in stoppage-time when Dany N'Guessan headed home to make it 3-3.

Mackay said: "In the first minute of the second half he [Helguson] showed his intent when he had the sliding chance and from then on he showed his maturity, he showed the fact he was a man coming into the game, he worked hard and his combinations with Danny Graham I thought were excellent."
