We take a look back at three players who have played for both clubs...
Coventry City take on Millwall on Saturday Afternoon in the Sky Bet League One fixture, as the Sky Blues look to get three points after a disappointing result last week.
Ahead of the game, we have taken a look at three players who have worn the colours of both clubs in years gone by.
The Canadian international arrived at Millwall in February 2014, after a spell with Bundesliga side Eintracht Braunschweig. His spell with the Lions would only last one year and it didn’t prove to be a fruitful one, as his game time was limited under then Lions' manager Ian Holloway.
Once the former Canadian Player of the Year departed the Lions in August 2014, he moved to the Sky Blues ahead of the 2014/15 season. The forward had a lot more game time at the Ricoh, but he was unable to make a lasting impression, eventually leaving the club at the end of the 2014/15 campaign.
The goalkeeper joined City in August 2005, on loan until the end of the year. He was the Sky Blues’ No. 1 during his time at the club. He kept three clean sheets as City drew five and won two of the 14 games he played in. However, an injury to Roy Carroll saw him recalled to his parent club West Ham United for the rest of the season.
Bywater moved to Millwall in June 2013. However, his game time with the Lions was very limited, as from February 2014 until the end of the season, he didn't feature at all for Millwall.
Dublin joined the Sky Blues in 1994, and in his four-and-a-half years with City, he would gain a reputation as one of the best strikers around. The 1997/98 season was perhaps the forward's best in a Sky Blue shirt. After helping City survive relegation the season before, Dublin formed a formidable partnership with Darren Huckerby. He finished the season as joint top scorer in the Premier League alongside fellow Englishmen Chris Sutton and Michael Owen, with 18 goals. The 1997/98 season would also see City finish in their highest ever league position, as they ended the campaign 11th in the Premier League table.
In the autumn of 1998, Dublin moved to local rivals Aston Villa. It was in 2002 when Dublin faced competition from Juan Pablo Angel and Peter Crouch for a starting berth at Villa, that he moved to Millwall. His two league goals in five games helped the Lions into the Play-offs, but they lost to Birmingham in the semi-final. He later returned to Villa, and remained there up until 2004, when he joined Leicester City on a free transfer.
