Stuart Armstrong has been called up to Scotland's national side

Dundee United have rejected bids from Celtic and Premier League side Burnley for midfielder Stuart Armstrong.

Celtic's offer for the 22-year-old is around £1.5m, with Burnley's believed to be slightly less.

The Tangerines knocked back both bids because they value the former Scotland Under-21 international at around £2.5m.

A United spokesman said: "Neither of these bids is anywhere close to our valuation. Neither bid is nearly close enough to consider."

Armstrong has won 20 caps for Scotland's under-21 side and was called up to Gordon Strachan's national team in 2013.

The player's lawyer, Liam O Donnell, told BBC Sport: "Stuart is ignoring all speculation about his future and simply concentrating on his football.

"He has a major cup semi-final at Hampden on Saturday and that is entirely what his mind is focused on."

The Inverness-born player, admired for his flair and creativity, has also scored six goals for United so far this season.
