Marco Silva has challenged Hull to build their future around star centre-back Harry Maguire. The 24-year-old's man of the match turn at Southampton helped secure a priceless point in the battle to beat the Premier League drop.Eldin Jakupovic's penalty save ensured a goalless draw at St Mary's on Saturday, helping to confirm Sunderland's top-flight relegation.Maguire again caught the eye however, leading boss Silva to admit Hull must fight to retain his services and shape their team around the in-demand defender."Of course it's important," said Silva, when asked if Maguire should play a pivotal role in Hull's future."He is a young player as well, and it's important for Hull to keep these kinds of players."There have been no offers for the player, so I don't want to talk too much about his position."I want to talk about the players keeping focused on our goal and to keep going until the end of the season."Jakupovic's added-time save from Dusan Tadic's penalty leaves Hull still able to control their Premier League fate, with the 32-year-old goalkeeper admitting Saturday's spot-kick heroics might prove the most important of his career."I've saved a lot of penalties in my career but this is for sure one of the main penalties, "said Jakupovic."Before the game I did my homework (on Tadic's penalties) with my goalkeeping coach."But to be fair I saw his four or five last penalties and he never finished like that."Finally, finally I had to make the decision. My feeling, my stomach told me to go this side."When the referee gave the penalty I said to myself 'come on now, you have to help the team again'. I spoke with myself 'come on', and finally I did it. "You have to be lucky as well because it was a very good penalty. It was a mix of luck with feelings and finally we took the point."
