Stevie May has been linked with both Dundee clubs but St Johnstone are the only Tayside team to confirm their intent to sign the Aberdeen striker.
In Spain Dens Park boss James McPake laughed off reported interest in the forward, saying: “I would love Stevie May!
“He’s a great player and, hopefully, he will in training with us on Monday…”
Courier Sport understands that May is on United’s radar but they have other transfer priorities at the moment.
Robbie Neilson’s number two, Gordon Forrest, was reluctant to speak about a potential target.
He said: “I don’t know much about that. I think the club will be linked with good players. “
Midfielder Pablo Ganet played as a trialist for United in their 6-0 win at Brechin on Friday night and Forrest said: “Pablo had lots of energy and good touches. It was good to see him in that environment. He did well.”
Adam King, brother of former United player Billy, was another trialist. The former Swansea midfielder got 15 minutes of action.
