West Brom head coach Alan Irvine has revealed that he had not seen record signing Brown Ideye live before signing him.
Manchester City will look to tie up a deal for teenage playmaker Kelechi Iheanacho when they return from their US tour.
Gary Mackay-Steven insists he is happy to stay at Tannadice after watching two former team-mates discover the grass is not always elsewhere.
The Scotland Under-21 international is one of the Scottish Premier League's hottest properties and has capped a sensational season with a nomination for the Cheque Centre PFA Scotland young player of the year award.
His dazzling ball skills have already attracted attention from npower Championship side Huddersfield, who failed with a combined £1.25million bid for the 22-year-old and team-mate Johnny Russell last summer.
Russell was the subject of another £380,000 bid by Italian outfit Catania earlier this month that was also knocked back and Mackay-Steven says he is in no rush to move on.
Former Arabs colleagues Scott Allan and David Goodwillie - now at West Brom and Blackburn - both quit the SPL hoping to progress their careers south of the border.
But neither player has found life in England easier, leaving Mackay-Steven to insist: "I'm not thinking about moving on. I just take every game as it comes and I'm quite happy here.
"We've got a great young team that has been doing well and I feel quite settled, so I'm definitely enjoying my football.
"The main thing is to be happy and enjoying your football, which I am at United. Things are going well so, definitely, the grass isn't always greener elsewhere."
As for Russell, the 20-goal striker took to Twitter to insist he had not asked for a move away from Tayside after United released a statement criticising the behaviour of his agent.
But Mackay-Steven in not surprised to see his team-mate attracting offers.
He said: "I'm not surprised big teams are interested in Johnny, he was banging in the goals before he got his injury.
"I haven't really spoken to him about it, we don't really speak about that, we just have a laugh. But having a big club in Italy interested in him just shows how well he's done this season."
United's 3-1 defeat to Motherwell last Friday leaves Jackie McNamara's men seven points behind third-placed Inverness and with only an outside chance of pinching the final Europa League slot with four games remaining.
But Mackay-Steven remains hopeful.
"There is a chance we could still get into Europe," he said.
"There's not many games left and it's tight from third down to sixth. But if we can get a little run together from now until the end of the season that would be great and a Europa League place would be an added bonus."
Standing in the way of Mackay-Steven and his colleagues are First Division champions Ross County, who have impressed many by securing a top-six finish in their first season in the top flight, including the United winger.
"I've not been too surprised," said Mackay-Steven ahead of tomorrow night's meeting in Dingwall.
"They have been difficult to beat and have a lot of good players.
"It will be a really tough game but we went up there and won 2-1 earlier this season and we'll be looking to repeat that."
