Tottenham loanee Japhet Tanganga is turning himself into a hero under Millwall manager Neil Harris after his late header snatched a crucial victory over fellow Sky Bet Championship strugglers Birmingham.

It was a second goal in Lions colours for Tanganga, 24, who scored the first goal of his senior career in Harris’ first game back in charge at Southampton two weeks ago.

Millwall have now won three of their four games under Harris, who has quickly turned around their form to open up a five-point gap between them and the relegation zone.

Harris said: “Japh’s got great pedigree, he’s got a great CV in terms of games at the top level and playing in Europe, and things like that.

“It’s slightly different here for a centre-half and sometimes you have to be a different player here, and the reason I’m at the football club is to try and teach the players what a Millwall player looks like, whether that’s a goalkeeper or a centre-half or a centre-forward.

“All I said to Japh was – not complicated his game – just to make your decisions and I’ll support you, but you can be as aggressive as you like.

“A couple of his tackles were a little bit dubious here against Watford and away at Southampton in the first five minutes, but he shows that he’s buying into it.

“Ultimately, he’s headed the ball a lot (in both boxes) and to be a good Millwall centre-half you have to do that.”

Millwall started the better side, with Birmingham goalkeeper John Ruddy having to make good saves to deny George Honeyman and Jake Cooper in the first 20 minutes.

Jay Stansfield was then denied by Matija Sarkic just before half-time and hit a great chance wide early in the second half.

He then felt he should have been awarded a penalty after 63 minutes when Millwall’s Joe Bryan appeared to hold him back from Juninho Bacuna’s corner.

The Lions wildly celebrated when their winner came in the 90th minute as Tanganga rose to head in George Saville’s corner.

Birmingham remain only one point above the bottom three and caretaker boss Mark Venus has just one point from four games since taking the reins after manager Tony Mowbray temporarily stepped aside for medical reasons.

Venus, whose side could drop below third-from-bottom Huddersfield if they beat West Brom on Sunday, said on the Blues’ penalty shout: “I don’t want to sit here and pick holes in officials.

“They are what they are in this country and I’m sure everyone has their own opinion of them.

“Everyone has their own opinion of what happened, the incident, and they can make their own mind up.

“I think in the second half we got on top.

“I think in the first half we were too timid, we didn’t influence, we didn’t hurt their goal enough and I think in the second half we had a lot more purpose, more intensity.

“We took the game to them and we had some opportunities to hit the target, to score, to shoot, and we squandered them, really.

“I think they’ve got the stomach for the fight – they showed that in the second half.

“I think they just have to learn to do the basics a bit better and learn to make the right decisions.”

Japhet Tanganga headed in a 90th-minute winner as Millwall snatched a vital 1-0 victory over fellow Sky Bet Championship strugglers Birmingham.

The Lions have won three of their four games since Neil Harris returned to the club for a second spell as manager, although they had to withstand some heavy pressure from the Blues in the second half at The Den.

But a dogged display was eventually rewarded as Millwall opened up a five-point gap between themselves and the relegation zone and left Birmingham still just one point above the bottom three.

Millwall had the game’s first big chance in the 11th minute when George Honeyman played a one-two with Duncan Watmore to go through on goal, but his attempted dinked finish was blocked by John Ruddy.

It came in the middle of a good spell for the Lions, with the Birmingham goalkeeper and captain again coming to his side’s rescue when he clawed away an effort from opposing skipper Jake Cooper.

Ruddy was fortunate, however, when he was beaten to the ball, following a ricochet off Michael Obafemi, by Watmore whose header dropped comfortably wide.

Another Birmingham header then went unpunished when a loose headed clearance by Marc Roberts dropped for Zian Flemming, who could only shoot tamely at Ruddy from outside the area.

It took the Blues 41 minutes to muster a chance of their own when Koji Miyoshi’s through ball played in Jay Stansfield and his shot from a tricky angle needed tipping away by Matija Sarkic.

Another opening for the visitors quickly followed when Alex Pritchard sent an effort wide from just outside the box as neither team could break the deadlock before half-time.

Having finally played themselves into the game towards the end of the first half, it was Birmingham who had the first opening after the restart as Lee Buchanan sent a rising shot wide.

Another good opportunity for Stansfield then came and went when he shot wide from inside the area after his initial shot from Juninho Bacuna’s cross had been blocked.

The Blues were then left furious when they weren’t awarded a penalty in the 63rd minute when Stansfield appeared to be held back from Bacuna’s corner by Millwall’s Joe Bryan.

The visitors continued to dominate the second-half proceedings, with Stansfield shooting off-target again from a presentable shooting position.

From nowhere, Millwall found a second wind and finally had another chance of their own when Flemming’s long throw ran for George Saville, who headed over with 15 minutes remaining.

Just when it looked as though the match would end in stalemate, the Lions snatched all three points when Tanganga rose to head in Saville’s corner and spark wild celebrations from the home supporters.

Sammie Szmodics salvaged a point for Blackburn but his 20th Championship goal of the season could not disguise the home side’s frustration after a tough 1-1 draw with Millwall at Ewood Park.

Szmodics pounced on a defensive error to fire home just past the hour mark, 10 minutes after Millwall substitute Michael Obafemi had lashed the Lions in front.

But the result extended Rovers’ dismal streak to just one win in 15 league games and leaves John Eustace still searching for his first victory in charge.

In contrast, Millwall’s point stretched their unbeaten run under Neil Harris to three matches and they will arguably have been the happier, despite the careless manner in which they tossed away over an hour of sterling defensive work.

Revitalised under the charge of their all-time record goalscorer, the visitors had the best chance of a first half that was almost devoid of incident, Ziam Flemming shooting into the side-netting from a tight angle after George Saville’s corner.

It was the only chance of any kind mustered in the first half by Harris’ men, who seemed happy to sit back and squeeze the momentum out of the home side, with Japhet Tanganga in particular outstanding at the back.

The Lions’ tactics could largely be said to have worked if the scattered boos that greeted the hosts at the half-time whistle was anything to go by.

Szmodics could do nothing with an effort from a tight angle after being put through by Tyrhys Dolan, then Szmodics returned the favour but his team-mate was caught offside.

The busy Dolan tried his luck from long range but his effort was blocked by Tanganga, who was also central to hacking away a dangerous Dom Hyam free-kick, before Flemming had his chance at the other end, just before the half-hour mark.

Jake Cooper denied Szmodics a shooting chance with an excellent interception, then Ryan Longman’s gutsy counter-attack trickled out to neatly sum up a forgettable first period.

Obafemi needed less than eight minutes to make an impression, tenaciously winning Billy Mitchell’s fine cross into the box and capitalising on poor Rovers defending to turn and fire a rising shot past home goalkeeper Leo Wahlstedt.

Amid evident frustration among the home fans, Rovers responded well, Szmodics forcing a save from Matija Sarkic before a desperate blunder from Millwall’s Danny McNamara led to their 63rd-minute equaliser.

The full-back failed to spot Rovers substitute Amor Sigurdsson when playing a square ball and the Iceland striker, who had only been on the field for two minutes, served Szmodics to sweep the leveller past Sarkic.

The excellent Tanganga headed away a dangerous cross under pressure from Szmodics, while Yasin Ayari’s long-range effort deep into injury time was palmed away by Sarkic as Millwall held on.
