Nigerian striker Emeka Christina slammed a hattrick while midfielder Jumratul Islam Mithu struck twice as the black and whites bettered their 7-1 humiliation of Rahmatganj in the first leg at the same venue.

Captain Mwach Ukwu Paul regained his top scorer's position with one goal while fellow Nigerian defender Peter Odafe added the other as the hosts consolidated their position in the table with their first win in the second leg.

Mohammedan lead the pack with 26 points after 14 outings while Chittagong Mohammedan, who slumped to their third consecutive loss in the second part, stuck to 17 points from 13 matches.

Although title contenders Muktijoddha, Abahani and Sheikh Russel have the chance to replace Mohammedan from the top by the end of the ongoing 15th week, Shafiqul Islam Manik's boys have the comfort of having played all but one big match, against Brothers Union.

Unlike the two namesakes' first-leg clash in Chittagong, which ended in a goalless draw in last March, it was a one-way traffic at the muddy and a slowish Bangabandhu National Stadium.

The visitors however, rushed early blood when Dipu's left side cross picked up Yusuf, who shot the ball straight to goalkeeper Himel from six yards.

Chittagong Mohammedan kept the momentum for some time before the home side opened the floodgate through an apparently offside goal in the 15th minute.

Emeka, who missed their last game against Abahani due to suspension, was standing alone inches out of the line and tapped the ball home after Mithu managed to get the ball beyond goalkeeper Tito after his fist two attempts came off the bar and the keeper respectively.

Mohammedan never looked back in the embarrassingly one-sided game and Emeka doubled the lead five minutes later with a backheader from 12 yards after the port city defence partially cleared a high ball by Sharif.

There was no respite and Paul scored his 13th league goal in the 21st minute when the robust striker, who raced inside with a through from rightback Kamal, hammered the ball into Tito's near post shrugging off a challenge by Saikat.

Emeka completed his treble eight minutes before the break when the yellow-haired cut in with Belal's through down the left and neatly placed the ball into the far corner.

The other players to score hattricks in the league are Muktijoddha's Alfaz, Mohammedan's Paul and Brothers' Junior -- all against Rahmatganj -- but the latter has also struck a treble against Khulna Abahani.

The boys from Chittagong showed some spirit even after going 4-0 down and Zahid twice threatened to reduce the margin immediately after resumption. But he mistimed his effort from a handshaking distance before forcing the only save by Himel, who tipped over a top-of-the-box.

Mohammedan regained their appetite for goals on the hour when Paul forced a corner and the resulting flag-kick was headed in by Mithu to make it 5-0.

The diminutive medio hit the crossbar before getting his second, finishing a one-two move with Paul off a deflection in the 71st minute while an overlapping Odafe exchanged passes with substitute Asad before sealing the victory one minute from time with a low drive from 15 yards.
