ADAM Armstrong described as "unbelievable" the chance to join Saints.

Armstrong completed a move from Blackburn Rovers on Tuesday, for a fee the Daily Echo understands to be around £15million.

The 24-year-old scored 29 goals in the Championship for Rovers last season, but is now back in the Premier League again having last played in the top flight with Newcastle in the 2014-15 campaign.

Discussing his move to Saints, Armstrong said: "It’s unbelievable to be here – such a massive club with a great fanbase and it’s just something that I’m really looking forward to.

“I thought it was perfect as my next step. I wanted to get back to the Premier League from what I’ve done for Blackburn, so I’m over the moon.”

Armstrong became the second striker to join Saints today, following the arrival of Armando Broja on loan from Chelsea.

They will compete with the likes of Che Adams, Shane Long and Michael Obafemi for a starting berth.

However, Blackburn boss Tony Mowbray yesterday confirmed the club are interested in bringing Obafemi to Ewood Park, to replace Armstrong. Some reports suggest Saints and Blackburn have agreed a fee for Obafemi, with the striker now to decide if he wants to leave.

Nathan Tella, Theo Walcott and Nathan Redmond were all used as striker options at Saints at times last season.
