Pakistan's aggressive bowing attack seems to be under pressure against quality batting lines, said former captain turned cricket commentator Ramiz Raja after his side tumbled to a seven wickets loss against England in the one off T20I at Cardiff on Sunday. “Our bowling unit is failing to defend totals, which is an area of concern because when our bowling line doesn’t manage to take wickets then they shift to defensive bowling, which is not a particularly strong area of the Pakistani bowlers.” “Until we learn the art of bowling defensively, which is made up of bowling variations, slower bouncers and a mixture of other deliveries, Pakistan would not become a formidable team outside the Asian conditions,” said Raja, at Ramiz Speaks. The former captain added that Pakistan needs to work on all the departments, especially on its bowling. “Our bowlers got hit for a boundary in all but three overs, which is why we were not able to create pressure on the opposition and this game is all about creating pressure,” said Raja. Pakistan is set to play five-match ODI series against England from May 5. The squad will then kick off two warm-up World Cup games against Afghanistan on May 24 and Bangladesh on May 26, before taking on the West Indies in their first World Cup match in Nottingham on May 31.
