The prolific forward has been Wilson's priority signing for months, although he has faced opposition from Ajax for his signature. However, Mols's decision to travel to Hillsborough is seen as a promising development by Wednesday.
Wilson wants Mols in the side immediately and he could make his debut against Leeds on Saturday if the formalities are completed.
The West Ham manager, Harry Redknapp, is similarly seeking to enhance his strike force, but from further afield. Redknapp has stepped in for the Paraguayan striker Miguel Dominguez, after Middlesbrough stalled on signing him.
The 19-year-old played for the Hammers' reserves yesterday and could join on loan for the rest of the season in a precursor to a permanent move. Dominguez can come to England on a short-term contract as he has an EU passport and so does not need a work permit.
John Gregory will make a decision later this month on whether Stan Collymore should be allowed to stay away from Aston Villa until he has recovered from clinical depression.
The pounds 7m striker is having treatment at a psychiatric hospital three days a week and spending two days with Villa. But it may be that he will be left to concentrate fully on his treatment until he has recovered.
Gregory, the Villa manager, said: "I have told him that I am quite willing to see how he copes for the next fortnight. It is a unique situation.
"I have to make the decision whether we continue as we are, where he is only making a bit-part performance, or decide to have him full-time at the clinic. That would mean not seeing him at the training ground at all.
"Then it is down to the money men to deal with the financial commitments that Aston Villa have to the player. The board and myself as well as Stan and his representatives have to come up with a solution in the forthcoming weeks."
Gregory added: "Stan has to receive the treatment. He has the rest of his life to cope with and we are helping him in that direction as much as we can."
Stan Ternent has refused to resign as manager of Burnley, but faces the sack in the next 48 hours. Ternent met the club chairman, Barry Kilby, yesterday after a record 6-0 home defeat by Manchester City, but insisted he will not resign.
He has more than two years left on his contract and would want a pay- off. The board were in discussions about his future last night and are likely to dismiss him before making a quick approach for a replacement.
n England's Under-18s put eight goals past their Andorra counterparts for no reply in Spain yesterday. The England juniors outclassed their inexperienced European Championship group opponents, who had no answer to the skill and physical stature of David Platt's side. The victory kept England, who drew their opening match 1-1 with Spain on Monday, on course to qualify for next month's two-legged intermediary round. England will complete their group programme against Israel tomorrow at the same time as Spain face Andorra.
