Southampton have announced that they have signed Adam Armstrong from Championship club Blackburn Rovers.

The Saints have stated that the former Newcastle United striker has signed a four-year contract with the Premier League club.

The 24-year-old striker has reportedly cost Southampton £15 million in transfer fees.

The former England Under-21 international scored 28 goals and gave five assists in 40 Championship matches for Blackburn last season.

During the 2019-20 campaign, Armstrong found the back of the net 16 times and provided six assists in the Championship.

Southampton manager Ralph Hasenhuttl told the club’s official website: “Adam was a big target for us this summer, so we are very pleased to have added him to the squad, especially as there was a lot of interest in him from other clubs too.

“He is at a good stage of his career for him to be coming here. He is a young, dynamic player who has developed well so far and already has good experience, as well as an impressive goalscoring record, and I believe we can now help him realise even more of his potential.

“He will bring a lot of qualities to our team, and he gives us another good option in attack, which will be important for us.”

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.”

Southampton can be backed at 9/5 on Betfair to finish in the top half of the Premier League table this season.
