Eddie Nketiah had the first opportunity to score just a minute in, but saw his drilled strike tipped wide by Daniel Iversen for a corner.
Not long after, the Foxes soon created their own chance on goal, when George Thomas sent a low shot from the edge of the penalty area narrowly wide of the far post.
Although Tye visitors had enjoyed the opening exchanges of the game, it was Steve Gatting’s side who took the lead on the half-hour mark when Osei-Tutu broke free down the right channel and fired in a dangerous ball. With Chuba Akpom waiting, Darnell Johnson inadvertently put the ball into his own net.
