Former England pacer Stuart Broad believes India's bowling attack, barring Jasprit Bumrah and Mohammed Siraj, requires major retooling for the final Test of the England series at the Oval, starting July 31. The visitors secured a hard-earned draw in the fourth Test at Manchester but still trail the five-match series 1-2.While the batting has been impressive throughout the series, the Indian bowling has been inept for the most part. The bowlers conceded a massive 669 to the hosts in their lone bowling innings in the Manchester Test.Talking about India's bowling lineup for the all-important Oval Test, Broad told Sky Sports (8:50):"He (Bumrah) needs some help from the other end. Siraj has tried his best throughout the series and has had moments of excellence. But the rest of that bowling attack didn't look really impressive. But the Oval will offer them more and bring the slips into play so you need a good bowling attack at the Oval."India conceded 600+ in an innings for the first time since 2014 in the fourth Test at Manchester. All but two of their six bowlers gave away over 100 runs in a disappointing display with the ball."You can't take the bowler out of the equation" - Stuart Broad on Jasprit Bumrah playing at the OvalStuart Broad believes Jasprit Bumrah must have a massive say in his participation for the final Test against England at the Oval. The 31-year-old has already reached his pre-series threshold of three Tests with one game remaining.However, with India in with a chance to level the series, all eyes are on Bumrah to find out if the ace pacer will play a fourth Test in the series."You can't take the bowler out of the equation ( in the decision). He is the only one who knows how his body is to get through another Test match. Crucially, he's only bowled once, which is a big difference," said Broad (via the aforementioned source).He added:"Shubman Gill has to sit down with his main strike bowler and go, 'How are you feeling? The Oval pitch will suit you more than Old Trafford, so, can you give us something without feeling like you are breaking?' If he has niggles with his ankle or sides, then he's declaring himself unfit to play Test match cricket."Bumrah endured a rare off-game in the Manchester Test, conceding 100+ runs in an innings for the first time in his stellar 48-Test career. Yet, he remains India's joint-leading wicket-taker in the series with 14 at an average of 26 despite missing the second Test at Edgbaston.
