Ones to watch
The striker is Luton's top goalscorer in the Championship but despite only scoring twice in 2021, Collins is one of the Hatters' biggest attacking threats.
The 30-year-old is a difficult man to get off the ball especially when holding it up.
The attacker has scored seven goals so far this season for the Lions, and will look to enter double figures on his goal tally again in the Championship.
Starting on the left in the front three, Wallace is a key asset to Millwall's attack. He's a threatening player going forward and always one the opposition should be wary of.
