Spurs boss hoping to unearth a proven goalscorer

Important

Harry Redknapp admits it is important for Tottenham to add new signings this summer if they are to challenge for UEFA Champions League qualification in 2011/12. Spurs got a taste of Europe's premier club competition this season and are keen to return to that stage in the near future. For now, though, they will have to make do with the consolation prize of a place in the Europa League, with a 2-0 victory over Liverpool on Sunday putting them in pole position to secure a fifth-placed finish. Redknapp believes his side tumbled out of the top-four reckoning as they were unable to handle the rigours of Premier League and Champions League competition, but he has every intention of constructing a squad which can cope with those demands in the future. "There are six teams (challenging) for that top four," he said. "Manchester United are certainties, Chelsea are certainties and you have to fancy Man City next year as they are going to spend another £100million. "You also have to fancy Arsenal, because they have been there every year, and Liverpool are a great club with great tradition and they will be back stronger with Kenny (Dalglish) next year. "We could have improved (the squad) in January. It wasn't a case of spending, we just needed a little tweak to liven us up a bit because we had a few tired players around."We then lost key players: (Gareth) Bale was flying at the time and winning games for us but we weren't scoring while Rafa (van der Vaart), who had been looking like a £50million player all season, tired in the last six or seven weeks and that was important for us. "Hopefully we can get one or two players in the summer and improve again for next year because it is going to be hard. "We have a big squad but what we need is one or two players who will make the difference to us. "Liverpool have done that with Luis Suarez, he is going to be a big player, and we need to find one or two to keep us pushing for the top four." Top of Redknapp's shopping list will be a proven goalscorer, with Jermain Defoe, Peter Crouch and Roman Pavlyuchenko having failed to deliver the goods this season. "We have some players to shift now, we have players on loan who will be coming back and I'm looking for a good frontman if I can find one," he added. "I went to the cup final in France on Saturday night and I'm going to go abroad two or three times this week and keep following up leads and see what we come up with. "It's very difficult finding better than what you've already got."
