Cologne - Stopping Alexander Meier is only half of the job 1. FC Köln have on their hands when they welcome free-scoring Eintracht Frankfurt to the RheinEnergieStadion this Sunday (kick-off 17:30 CET / 16:30 GMT).

The 32-year-old rediscovered his goalscoring boots as the Eagles beat Hamburg last weekend, and Köln stopper Timo Horn is aware he has a battle on his hands to keep a clean sheet for the fourth time in five home matches.

Köln can sense the relegation zone creeping up on them as they prepare to welcome Frankfurt to a RheinEnergieStadion which has hardly provided them with many home comforts this season. Indeed, the Billy Goats have won only once in front of their own fans, and scored only five goals. Frankfurt are only six points better off, though, and cannot count themselves safe just yet.

Peter Stöger has no new injury concerns after the Billy Goats' DFB Cup defeat to SC Freiburg, although the 48-year-old could opt to rotate his side. Deyverson could replace Yuya Osako (r.) in attack after the Brazilian netted Köln's consolation at the Schwarzwald-Stadion on Tuesday night.

Nelson Valdez is back in training, but not yet ready to make his comeback from a serious knee injury, according to Frankfurt coach Thomas Schaaf. "He continues to complain about tiredness," Schaaf said. However, Peruvian defender Carlos Zambrano and Swiss striker Haris Seferovic (l.) are both back from suspensions.

It took more than four games to get past Horn (r.) at the start of the season, and while his goal has been breached a little more regularly since then, the Köln custodian has kept three clean sheets in his last four league appearances. Only Manuel Neuer and Yann Sommer boast better records since Matchday 19.

Two games without a goal could be described as something of a goal drought for a player of Meier's calibre, but the Eintracht fan favourite's scintillating form this campaign has raised expectations considerably. Frankfurt's top-scorer moved up to 16 for the season against Hamburger SV last weekend.

Peter Stöger (Köln coach): "Frankfurt have a very dangerous attack, but they've not looked the strongest in defence at times and that's where we've got to get at them. We can expect a difficult challenge, but we're looking forward to it and want three points."

Thomas Schaaf (Frankfurt coach): "We don't just want to play one good game, we want two, three or more to follow. It's about putting a run together. This game's not going to be an easy one for us to control."

Since beating Hamburg at the start of the new year, Köln have failed to win any of their last five league games, although they have lost only two of those. Frankfurt have lost just two since the turn of the year, picking up eight points in six games.

This is the 80th meeting between the two sides, although Frankfurt's 3-2 win in the reverse fixture was the first time they had met since 2011. Köln still edge the head-to-head statistics despite that defeat, with 28 wins to Frankfurt's 26. Last time in Cologne - in December 2010 - the hosts won 1-0 while Frankfurt's last win here was in May 1994.

Possible line-ups:

Köln: Horn - Olkowski, Maroh, Wimmer, Hector - Peszko, Vogt, Lehmann, Risse - Osako, Ujah

Frankfurt: Trapp - Chandler, Zambrano, Russ, Oczipka - Hasebe, Stendera - Aigner, Piazon - Seferovic, Meier
