Fans stunned as Sunderland 'agree' two deadline day deals that could guarantee they stay up

Sunderland's transfer activity on deadline day has left fans stunned as they have backed the newly-promoted club to stay in the Premier League.

Sunderland have been extremely busy during the summer transfer window after earning promotion to the Premier League last season.

Last season's Championship play-off winners have recruited several players, including Granit Xhaka, Habib Diarra and Chemsdine Talbi, among others.

And the club plan to back Regis Le Bris with further additions ahead of the window slamming shut today.

Sunderland are closing in on not one but two huge signings that has shocked fans online.

The club have reached an agreement with RB Leipzig for the signing of Lutsharel Geertruida, who will join on an initial loan deal with an option to buy, according to David Ornstein.

Geertruida is in Sunderland ahead of undergoing his medical.

The defender, 25, is a Dutch international and boasts Champions League experience, having made eight appearances in Europe last season.

Geertruida isn't the only Dutch player that is set to move to the Stadium of Light as Fabrizio Romano claims a deal is in place for Sunderland to sign Brian Brobbey from Ajax.

Brobbey, who was linked with Manchester United during Erik ten Hag's reign, is set to cost an initial £17 million, with the player set to undergo a medical.

The 23-year-old replaces Marc Guiu, who is returning to Chelsea following the injury to Liam Delap.

Guiu had signed for the Black Cats on a season-long loan, but the club have reached an agreement with Chelsea to end the deal.

Sunderland's deals for the Dutch duo sent social media wild as fans praised their business this summer, while tipping them to avoid the drop.

One X user wrote: "Sunderland really moving like a PL club on deadline day."

A second said: "Sunderland are staying up."

A third added: "Sunderland is more ambitious than a lot of PL teams."

A fourth commented: "Sunderland ain't playing.. They don't want to go down."

Sunderland have won two of their three opening league fixtures this season.

They beat West Ham United on the opening weekend before securing a dramatic win over Brentford last weekend.
