text: It's that time of year when football managers double as mathematicians. With points running out and prizes at a premium, they're praying the calculator tells them the dream is still alive. But for those at the top of a claustrophobic Championship, the maths is simple — win every game or risk missing out on a potential £120million payday. Two points separate four teams, with four games remaining. To drop points would almost certainly mean to drop out of the race for the two automatic slots to the Barclays Premier League. Middlesbrough were top on Good Friday but are fourth going into the visit of Wolves. Aitor Karanka is not wasting his time on permutations. Lee Tomlin (centre) fires Middlesbrough 1-0 ahead against Rotherham United in the Championship match . Middlesbrough boss Aitor Karanka (right) is targeting wins from all of his side's remaining fixtures this season . 'We have to win our games,' said the Spaniard. 'I think by winning four games we will get promotion, but it is very difficult. We have to forget the other teams and just concentrate on our games.' Wolves are seven points behind Boro but only outside the play-offs on goal difference after Saturday's 2-1 defeat to Midlands rivals Birmingham. And head coach Kenny Jackett admits they have played must-win games for a while. He said: 'It seems to have been that way for about three months, where we have been chasing. 'We have been working hard to make sure the sides at the top don't get away. It's good we're in this position. We want to be a Premier League club.' Callum Wilson (left) is congratulated after scoring his side's second goal against Brighton in their last game . Bournemouth boss Eddie Howe insists that his side are not getting carried away at the top of the table . The Championship leaders Bournemouth travel to Reading. And the message from Eddie Howe to his team is very much: 'Don't get ahead of yourselves'. 'With every win, we take it away from some of the teams that have been challenging all season, but I still think it is anyone's,' said Howe. 'We have to focus on every game, not get complacent, and remember that this league has a habit of throwing up surprises. We want to make sure that we stay strong until the end.' Norwich are the division's form team having won four on the spin and, ahead of their trip to Leeds, manager Alex Neil said: 'My job is simple. I said it before (Saturday's 2-1 win at Bolton) we had five left and we had to win every one. Now we have four it's the same.' Bolton Wanderers' Josh Vela (left) and Norwich City's Nathan Redmond (right) battle for the ball . Watford are the team sandwiched in third and they have the benefit of seeing how their rivals perform before they take on Nottingham Forest at the City Ground on Wednesday. The leading quartet could all guarantee their place in the play-offs at least with midweek victories. But for the chasing pack, four must go into two. Derby, Ipswich, Brentford and Wolves are within just one point of each other and must produce title-winning form between now and May 2 to be sure of post-season participation. Meanwhile, matters at the bottom of the table have been complicated after Rotherham were charged yesterday with fielding an ineligible player. Derby loanee Farrend Rawson played in their 1-0 win over Brighton on Easter Monday but there is confusion as to whether the defender had already been recalled. Rotherham are seven points above the drop zone and will nervously await the outcome of their FA hearing, especially if Millwall — with a game in hand — narrow that gap to four with victory over fellow strugglers Wigan. Elsewhere in the Football League this week, Bristol City will be Championship-bound with a win at Bradford City, while Jimmy Floyd Hasselbaink's Burton Albion side and Shrewsbury could leave League Two behind them if they triumph against Carlisle and Bury respectively — and other results go their way. Derby County striker Darren Bent turns to celebrate scoring a late equaliser against Brentford .
