First, regarding Fletcher: He brings much more to a side than just goals. He is a striker who can play as a target man and win first headers, or play on the quick counter attacks as he did in a few Sunderland this season. He is an excellent finisher, but he can also set up other players. He can drop off and get involved in the build up, and his link up play is excellent. Second, regarding your view on strikers: It simply doesn't work in the PL. Although it is a vital role of the striker, he can't just score goals. he needs to assist, to make spaces for other players, to drop off and get involved in the passing when the opposition stack the box, and most of all he needs to defend. Each team has a defensive system that involves all 11 players on the field and breaks down if one of them does not do his job. The striker needs to press the center-halves, cover for his wingers if needed, and defend set pieces. For example, how many goals from set pieces did we concede last season or the one before when Drogba was in the team? Very, very few. And the reason is that DD is always the man that attacks the ball when defending which leaves our CBs to mark their men comfortably. It's something that does not show up in stats, but is vital for the team.
