Indeed, on their own turf Hull have become nigh-on impenetrable post Silva's arrival, mustering five wins and one draw from six games at the KCOM Stadium.

Hull - who were bottom when Marco Silva took over in January - moved out of the relegation places, two points ahead of Swansea - who conceded three late goals to lose 3-1 to Tottenham.
But a well-deserved three points were wrapped up by Maguire's first league goal for Hull - plunging Boro further into the mire with Steve Agnew's men seven points adrift of safety.
Last night may have brought the attacking football the Boro fans had craved for so long, but it was to no avail. Not this one, however, as Hull began the match on the front foot and had the ball in the net within three minutes as Markovic squared the ball to Niasse, who had strayed offside, so his goal was disallowed.
"That's 'can we score a goal?' but also know clean sheets can help us win games".
It was an encouraging start from the home side, but they soon found themselves behind.
Ben Gibson failed to deal with a deflected looping cross from Andrew Robertson and Markovic took advantage to toe-poke home from close range.
Alfred N'Diaye hooked the ball forward and Hernandez's headed pass fell invitingly to Niasse, who buried his shot under Boro goalkeeper Victor Valdes from 12 yards. "The players remarked on the noise they made in the far corner".
Boro were stunned and needed some invention to get back in the game and Rudy Gestede almost provided that but he saw his header tipped onto the crossbar by keeper Eldin Jakupovic.
Maarten de Roon pulled a goal back for Middlesbrough in first-half stoppage time but Harry Maguire's header from a free kick in the 70th restored Hull's two-goal cushion.
Reflecting on the performance, Gibson said: "We didn't play the way we wanted to, or should have".
The pace, understandably, slackened after half-time, but the game remained remarkably open with chances at either end. The great escape really might be on after all in the East Riding.
Goals from winger Lazar Markovic, strikers Oumar Niasse and Abel Hernandez, and defender Harry Maguire ensured Hull's second consecutive league win and extended their unbeaten home run to eight games in all competitions.
