Manchester United midfielder Ander Herrera has welcomed Bastian Schweinsteiger and Matteo Darmian to the club after huge day for the Premier League giants in the transfer market.

On Saturday 13 July, Bayern Munich confirmed Schweinsteiger, 30, had informed them of his decision to leave the Allianz Arena to reunite with former manager Louis van Gaal at Old Trafford.

United later confirmed a deal is in place via their official website, pending a medical which is expected to be held today.

Later that evening, the club unveiled Italy international Matteo Darmian, who completed his move from Torino for a reported fee of £12.5m from Torino, signing an initial four-year deal.

Both are likely to have a role to play in United's preseason tour of the US, which they fly out for on Monday.

While Schweinsteiger's move is not yet finalised, Herrera has praised the club's swift business, tweeting: "Welcome Bastian Schweinsteiger and Matteo Darmian. While others rest, we get stronger. Ready to #bethedifference."

Herrera's comments could be seen as a nod towards the lack of transfer activity emanating from their immediate rivals. While Liverpool have strengthened their ranks with six new players, the most notable being Roberto Firmino, Nathaniel Clyne and James Milner, Manchester City's only business so far has been the signing of 18-year-old Enes Unal.

Manuel Pellegrini's were reportedly on the brink of adding Aston Villa captain Fabian Delph to their squad on Friday only for the player to deny talk of an imminent move via a statement released on Saturday.

Arsenal, meanwhile, have strengthened considerably in one area having added Petr Cech to their ranks while Chelsea's only first team addition so far is Radamel Falcao. The Colombia international, who endured a disappointing loan spell at United last season, has signed for the Blues on loan from Monaco for the 2015-16 season.
