Liverpool boss Brendan Rodgers has played down Joe Cole\'s injury after the playmaker was substituted during the Reds\' 1-0 UEFA Europa League third qualifying round victory over Gomel. Cole, who spent last season on loan at Lille, lasted just 23 minutes before he was replaced by 17-year-old Raheem Sterling at the Central Stadion in Belarus. \"Joe just felt his hamstring a little bit,\" Rodgers said. \"I don\'t think it is totally pulled and it was just a little bit of tightness so we had to take him off. \"It disrupted our plans a little bit but it was better to have him come off rather than risk injury.\" Glen Johnson was replaced by Martin Kelly just one minute into the start of the second period, but Rodgers said that was a tactical move and not forced upon him. \"Glen was only scheduled to play 45 minutes anyway so he was taken off as planned,\" he added. Stewart Downing\'s second half strike meant Rodgers\' first competitive game in charge of Liverpool ended with victory, and the former Swansea boss was pleased with what he saw. \"It will take time until Liverpool start playing the way Swansea did last season (tactically),\'\' he said. \"Actually the way you play depends on the players you have. \"As for today I saw two things which were very important for me, I saw desire and commitment. I am very grateful to my players for a good game. Obviously it was a serious test of the players\' fitness and I am really happy with the result. \"This was my first competitive game in charge of Liverpool and for me it didn\'t really matter whether the game was played in Belarus or Brazil as I am really honoured to manage this side.\'\' And the Ulsterman was impressed with Gomel, who on another day could have emerged victorious after wasting plenty of chances in front of goal. Rodgers continued: \"This game was a great test for us at this point of the season. Today we saw that Gomel is a very good club which is already into the season. \"Their tactical idea was to defend and counter-attack so it was difficult for us to find the open spaces in the first half but at half-time I told my players to be patient and that the chances would come. \"After the first 45 minutes I also changed the structure of the midfield and Steven Gerrard started to play a bit lower than the other two central midfielders. \"I am glad that Stewart scored the goal as we put him on that side to come in and shoot. It was a great shot.\'\' From : Fifa
