Manchester United midfielder Ander Herrera has said he would welcome the arrival of new players at Old Trafford before the end of the transfer window after the club qualified for the the Champions League group stage. The Spanish star said he didn't know about Louis van Gaal's transfer plans but was optimistic, pointing out that last season both Radamel Falcao and Angel Di Maria arrived at Old Trafford in the final days of the market.

The Premier League giants have already spent around £80m ($125m) in the current transfer window to bolster the squad with the signing of Memphis Depay, Matteo Darmian, Bastian Schweinsteiger, Morgan Schneiderlin. They have also signed goalkeeper Sergio Romero. Van Gaal is expected to sign another forward to add more pace to his attack and there is speculation that he will try to strengthen defence following Sergio Ramos' decision to snub the club and stay at Real Madrid.

Chelsea have recently signed Pedro Rodriguez and Abdul Rahman Baba, while Manchester City have recently been linked with a big summer move by Wolfsburg winger Kevin De Bruyne. The Guardian reported that the current Premier League leaders are confident of closing the deal for an initial fee of £54m ($83.5m).

Asked during an interview with Cadena Cope whether United will respond to De Bruyne's possible move with more signings, Herrera said: "We'll see. There is still time before the end of the transfer window."

"Last year Falcao and Angel (Di Maria) transferred at the last minute – anything can happen. Players that arrive will make us even better, helping the club fight for the titles again."

United signed the Colombian striker on deadline day last summer while Di Maria arrived at Old Trafford from Real Madrid just days before, on 26 August. Herrera refused to name who could follow in the footsteps of Falcao and Di Maria in the final days of the current transfer window but admits the club are in a strong position to make new signings.

"[Van Gaal] doesn't tell the players anything about it. I don't know [if United will sign more players]. Every day there are new rumours because the club is economically very powerful but we don't know anything."
