The Red Devils’ transfer business so far has seen Andrey Santos arrive from Chelsea, Youri Tielemans from Aston Villa and Karl Darlow from Leeds United. There are likely to be more arrivals before the transfer window closes, but Manchester United go into their penultimate friendly of the season with just the three new first team signings. Maguire has seen Santos and Tielemans in action in training and friendlies already and has liked what he has seen.

He reckons the 22-year-old Brazilian has already made progress since joining the club, while he thinks 29-year-old Tielemans is primed to make a big impact instantly at Old Trafford after his £35m move. The centre-back played alongside the Belgian before leaving Leicester in 2019 and saw his quality up close even back then. ‘Andrey has been here since minute one of pre-season and he’s been amazing. You can really feel the progress he’s making already,’ Maguire told Manchester United club media. Andrey Santos was signed from Chelsea for £48m (Picture: Getty Images) ‘Youri, I played with him at Leicester for a few months so I know the ability and talent that he has. ‘He’s at an age now where he’s going to come in, I’m sure he’s not going to need settling in, he’s going to come in and be a big player for this club. He’s a top player, I know that.’ The England international also had praise for the character of Darlow, who is unlikely to play much football for Manchester United, but has come in to support first choice goalkeeper Senne Lammens. Tielemans was a shock arrival from Aston Villa this summer (Picture: Getty Images) The Wales international is out injured, but Maguire feels his presence is a positive one for the squad. ‘Karl is out for a little bit at the moment, but I know Karl, I’ve played against him numerous times over the years,’ he said. ‘He’s a great lad to have around the place, around the dressing room. ‘He can bring great leadership and value to the team on the pitch but also off the pitch as well.’ Harry Maguire with captain Bruno Fernandes after the draw with PSG (Picture: Getty Images) Manchester United’s pre-season preparations continue on Wednesday in Dublin against Leeds United, before a final friendly against AC Milan in Poland. Their Premier League campaign begins on August 22 against one of Maguire’s former clubs, Hull City. The defender has talked up an improvement on last season’s results, despite them being encouraging since Michael Carrick took charge in January. ‘There will be new ideas and different ways of playing. Last season, we played very well in certain matches, but we could have done better in others. We know that,’ he said. ‘The results and points were there, but we could have delivered better performances. We worked on it during the pre-season, and I think we’ll see better performances.’ Comment now Comments Add Metro as a Preferred Source on Google Add as preferred source
