Former Manchester United captain Roy Keane has paid tribute to Edinson Cavani for the Uruguayan's two-goal showing against Southampton in the Premier League on Sunday afternoon.

The 33-year-old was introduced at the half-time interval of the clash at St Mary's, with Ole Gunnar Solskjaer's side trailing 2-0 courtesy of goals from Jan Bednarek and James Ward-Prowse.

Cavani provided the assist for Bruno Fernandes to make it 2-1, though, before scoring twice in the final 15 minutes to secure a 3-2 victory for the 20-time English champions.

Keane has claimed that the South American could be "a huge signing for United", who have now been victorious in their last four matches in all competitions.

"He was obviously slow getting onto the pitch with those boots," Keane told Sky Sports News. "Just as well he did score because how the guy isn't prepared and ready to go on is mind boggling.

"Obviously he didn't need the boots in the end, he scored with two headers and had a great contribution when he came on. He obviously still has that quality, and the hunger and desire.

"It was always a gamble when he came to the club. People were doubting why he came to the club, did he have the hunger and desire? We've seen clips of him in some other games and we thought, 'Has he still got it?', but we've seen proof of it today, he could turn out to be a huge signing for United. It's worked out well today."

Cavani has now scored three times in five Premier League appearances for the Red Devils.
